SET DateStyle = 'Postgres, MDY';

Prevent internal overflows in date-vs-timestamp and related comparisons.
The date-vs-timestamp, date-vs-timestamptz, and timestamp-vs-timestamptz
comparators all worked by promoting the first type to the second and
then doing a simple same-type comparison. This works fine, except
when the conversion result is out of range, in which case we throw an
entirely avoidable error. The sources of such failures are
(a) type date can represent dates much farther in the future than
the timestamp types can;
(b) timezone rotation might cause a just-in-range timestamp value to
become a just-out-of-range timestamptz value.
Up to now we just ignored these corner-case issues, but now we have
an actual user complaint (bug #16657 from Huss EL-Sheikh), so let's
do something about it.
It turns out that commit 52ad1e659 already built all the necessary
infrastructure to support error-free comparisons, but neglected to
actually use it in the main-line code paths. Fix that, do a little
bit of code style review, and remove the now-duplicate logic in
jsonpath_exec.c.
Back-patch to v13 where 52ad1e659 came in. We could take this back
further by back-patching said infrastructure, but given the small
number of complaints so far, I don't feel a great need to.

All regression tests pass except for rules.sql (unrelated).
Implement "date/time grand unification".
Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.

Extend pg_cast castimplicit column to a three-way value; this allows us
to be flexible about assignment casts without introducing ambiguity in
operator/function resolution. Introduce a well-defined promotion hierarchy
for numeric datatypes (int2->int4->int8->numeric->float4->float8).
Change make_const to initially label numeric literals as int4, int8, or
numeric (never float8 anymore).
Explicitly mark Func and RelabelType nodes to indicate whether they came
from a function call, explicit cast, or implicit cast; use this to do
reverse-listing more accurately and without so many heuristics.
Explicit casts to char, varchar, bit, varbit will truncate or pad without
raising an error (the pre-7.2 behavior), while assigning to a column without
any explicit cast will still raise an error for wrong-length data like 7.3.
This more nearly follows the SQL spec than 7.2 behavior (we should be
reporting a 'completion condition' in the explicit-cast cases, but we have
no mechanism for that, so just do silent truncation).
Fix some problems with enforcement of typmod for array elements;
it didn't work at all in 'UPDATE ... SET array[n] = foo', for example.
Provide a generalized array_length_coerce() function to replace the
specialized per-array-type functions that used to be needed (and were
missing for NUMERIC as well as all the datetime types).
Add missing conversions int8<->float4, text<->numeric, oid<->int8.

-- timestamp with time zone, interval arithmetic around DST change
|
Future-proof regression tests against possibly-missing posixrules file.
The IANA time zone folk have deprecated use of a "posixrules" file in
the tz database. While for now it's our choice whether to keep
supplying one in our own builds, installations built with
--with-system-tzdata will soon be needing to cope with that file not
being present, at least on some platforms.
This causes a problem for the horology test, which expected the
nonstandard POSIX zone spec "CST7CDT" to apply pre-2007 US daylight
savings rules. That does happen if the posixrules file supplies such
information, but otherwise the test produces undesired results.
To fix, add an explicit transition date rule that matches 2005 practice.
(We could alternatively have switched the test to use some real time
zone, but it seems useful to have coverage of this type of zone spec.)
While at it, update a documentation example that also relied on
"CST7CDT"; use a real-world zone name instead. Also, document why
the zone names EST5EDT, CST6CDT, MST7MDT, PST8PDT aren't subject to
similar failures when "posixrules" is missing.
Back-patch to all supported branches, since the hazard is the same
for all.

Support +/- infinity in the interval data type.
This adds support for infinity to the interval data type, using the
same input/output representation as the other date/time data types
that support infinity. This allows various arithmetic operations on
infinite dates, timestamps and intervals.
The new values are represented by setting all fields of the interval
to INT32/64_MIN for -infinity, and INT32/64_MAX for +infinity. This
ensures that they compare as less/greater than all other interval
values, without the need for any special-case comparison code.
Note that, since those 2 values were formerly accepted as legal finite
intervals, pg_upgrade and dump/restore from an old database will turn
them from finite to infinite intervals. That seems OK, since those
exact values should be extremely rare in practice, and they are
outside the documented range supported by the interval type, which
gives us a certain amount of leeway.

Support +/- infinity in the interval data type.
This adds support for infinity to the interval data type, using the
same input/output representation as the other date/time data types
that support infinity. This allows various arithmetic operations on
infinite dates, timestamps and intervals.
The new values are represented by setting all fields of the interval
to INT32/64_MIN for -infinity, and INT32/64_MAX for +infinity. This
ensures that they compare as less/greater than all other interval
values, without the need for any special-case comparison code.
Note that, since those 2 values were formerly accepted as legal finite
intervals, pg_upgrade and dump/restore from an old database will turn
them from finite to infinite intervals. That seems OK, since those
exact values should be extremely rare in practice, and they are
outside the documented range supported by the interval type, which
gives us a certain amount of leeway.

Support +/- infinity in the interval data type.
This adds support for infinity to the interval data type, using the
same input/output representation as the other date/time data types
that support infinity. This allows various arithmetic operations on
infinite dates, timestamps and intervals.
The new values are represented by setting all fields of the interval
to INT32/64_MIN for -infinity, and INT32/64_MAX for +infinity. This
ensures that they compare as less/greater than all other interval
values, without the need for any special-case comparison code.
Note that, since those 2 values were formerly accepted as legal finite
intervals, pg_upgrade and dump/restore from an old database will turn
them from finite to infinite intervals. That seems OK, since those
exact values should be extremely rare in practice, and they are
outside the documented range supported by the interval type, which
gives us a certain amount of leeway.

Support +/- infinity in the interval data type.
This adds support for infinity to the interval data type, using the
same input/output representation as the other date/time data types
that support infinity. This allows various arithmetic operations on
infinite dates, timestamps and intervals.
The new values are represented by setting all fields of the interval
to INT32/64_MIN for -infinity, and INT32/64_MAX for +infinity. This
ensures that they compare as less/greater than all other interval
values, without the need for any special-case comparison code.
Note that, since those 2 values were formerly accepted as legal finite
intervals, pg_upgrade and dump/restore from an old database will turn
them from finite to infinite intervals. That seems OK, since those
exact values should be extremely rare in practice, and they are
outside the documented range supported by the interval type, which
gives us a certain amount of leeway.
Bump catalog version.

All regression tests pass except for rules.sql (unrelated).
Implement "date/time grand unification".
Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.

Support +/- infinity in the interval data type.
This adds support for infinity to the interval data type, using the
same input/output representation as the other date/time data types
that support infinity. This allows various arithmetic operations on
infinite dates, timestamps and intervals.
The new values are represented by setting all fields of the interval
to INT32/64_MIN for -infinity, and INT32/64_MAX for +infinity. This
ensures that they compare as less/greater than all other interval
values, without the need for any special-case comparison code.
Note that, since those 2 values were formerly accepted as legal finite
intervals, pg_upgrade and dump/restore from an old database will turn
them from finite to infinite intervals. That seems OK, since those
exact values should be extremely rare in practice, and they are
outside the documented range supported by the interval type, which
gives us a certain amount of leeway.
Bump catalog version.

All regression tests pass except for rules.sql (unrelated).
Implement "date/time grand unification".
Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.

Prevent internal overflows in date-vs-timestamp and related comparisons.
The date-vs-timestamp, date-vs-timestamptz, and timestamp-vs-timestamptz
comparators all worked by promoting the first type to the second and
then doing a simple same-type comparison. This works fine, except
when the conversion result is out of range, in which case we throw an
entirely avoidable error. The sources of such failures are
(a) type date can represent dates much farther in the future than
the timestamp types can;
(b) timezone rotation might cause a just-in-range timestamp value to
become a just-out-of-range timestamptz value.
Up to now we just ignored these corner-case issues, but now we have
an actual user complaint (bug #16657 from Huss EL-Sheikh), so let's
do something about it.
It turns out that commit 52ad1e659 already built all the necessary
infrastructure to support error-free comparisons, but neglected to
actually use it in the main-line code paths. Fix that, do a little
bit of code style review, and remove the now-duplicate logic in
jsonpath_exec.c.
Back-patch to v13 where 52ad1e659 came in. We could take this back
further by back-patching said infrastructure, but given the small
number of complaints so far, I don't feel a great need to.

Prevent internal overflows in date-vs-timestamp and related comparisons.
The date-vs-timestamp, date-vs-timestamptz, and timestamp-vs-timestamptz
comparators all worked by promoting the first type to the second and
then doing a simple same-type comparison. This works fine, except
when the conversion result is out of range, in which case we throw an
entirely avoidable error. The sources of such failures are
(a) type date can represent dates much farther in the future than
the timestamp types can;
(b) timezone rotation might cause a just-in-range timestamp value to
become a just-out-of-range timestamptz value.
Up to now we just ignored these corner-case issues, but now we have
an actual user complaint (bug #16657 from Huss EL-Sheikh), so let's
do something about it.
It turns out that commit 52ad1e659 already built all the necessary
infrastructure to support error-free comparisons, but neglected to
actually use it in the main-line code paths. Fix that, do a little
bit of code style review, and remove the now-duplicate logic in
jsonpath_exec.c.
Back-patch to v13 where 52ad1e659 came in. We could take this back
further by back-patching said infrastructure, but given the small
number of complaints so far, I don't feel a great need to.

All regression tests pass except for rules.sql (unrelated).
Implement "date/time grand unification".
Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.

All regression tests pass except for rules.sql (unrelated).
Implement "date/time grand unification".
Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.

Improve behavior of to_timestamp()/to_date() functions
to_timestamp()/to_date() functions were introduced mainly for Oracle
compatibility, and became very popular among PostgreSQL users. However, some
behavior of to_timestamp()/to_date() functions are both incompatible with Oracle
and confusing for our users. This behavior is related to handling of spaces and
separators in non FX (fixed format) mode. This commit reworks this behavior
making less confusing, better documented and more compatible with Oracle.
Nevertheless, there are still following incompatibilities with Oracle.
1) We don't insist that there are no format string patterns unmatched to
input string.
2) In FX mode we don't insist space and separators in format string to exactly
match input string.
3) When format string patterns are divided by mix of spaces and separators, we
don't distinguish them, while Oracle takes into account only last group of
spaces/separators.

Clean up formatting.c's logic for matching constant strings.
seq_search(), which is used to match input substrings to constants
such as month and day names, had a lot of bizarre and unnecessary
behaviors. It was mostly possible to avert our eyes from that before,
but we don't want to duplicate those behaviors in the upcoming patch
to allow recognition of non-English month and day names. So it's time
to clean this up. In particular:
* seq_search scribbled on the input string, which is a pretty dangerous
thing to do, especially in the badly underdocumented way it was done here.
Fortunately the input string is a temporary copy, but that was being made
three subroutine levels away, making it something easy to break
accidentally. The behavior is externally visible nonetheless, in the form
of odd case-folding in error reports about unrecognized month/day names.
The scribbling is evidently being done to save a few calls to pg_tolower,
but that's such a cheap function (at least for ASCII data) that it's
pretty pointless to worry about. In HEAD I switched it to be
pg_ascii_tolower to ensure it is cheap in all cases; but there are corner
cases in Turkish where this'd change behavior, so leave it as pg_tolower
in the back branches.
* seq_search insisted on knowing the case form (all-upper, all-lower,
or initcap) of the constant strings, so that it didn't have to case-fold
them to perform case-insensitive comparisons. This likewise seems like
excessive micro-optimization, given that pg_tolower is certainly very
cheap for ASCII data. It seems unsafe to assume that we know the case
form that will come out of pg_locale.c for localized month/day names, so
it's better just to define the comparison rule as "downcase all strings
before comparing". (The choice between downcasing and upcasing is
arbitrary so far as English is concerned, but it might not be in other
locales, so follow citext's lead here.)
* seq_search also had a parameter that'd cause it to report a match
after a maximum number of characters, even if the constant string were
longer than that. This was not actually used because no caller passed
a value small enough to cut off a comparison. Replicating that behavior
for localized month/day names seems expensive as well as useless, so
let's get rid of that too.
* from_char_seq_search used the maximum-length parameter to truncate
the input string in error reports about not finding a matching name.
This leads to rather confusing reports in many cases. Worse, it is
outright dangerous if the input string isn't all-ASCII, because we
risk truncating the string in the middle of a multibyte character.
That'd lead either to delivering an illegible error message to the
client, or to encoding-conversion failures that obscure the actual
data problem. Get rid of that in favor of truncating at whitespace
if any (a suggestion due to Alvaro Herrera).
In addition to fixing these things, I const-ified the input string
pointers of DCH_from_char and its subroutines, to make sure there
aren't any other scribbling-on-input problems.
The risk of generating a badly-encoded error message seems like
enough of a bug to justify back-patching, so patch all supported
branches.

Improve behavior of to_timestamp()/to_date() functions
to_timestamp()/to_date() functions were introduced mainly for Oracle
compatibility, and became very popular among PostgreSQL users. However, some
behavior of to_timestamp()/to_date() functions are both incompatible with Oracle
and confusing for our users. This behavior is related to handling of spaces and
separators in non FX (fixed format) mode. This commit reworks this behavior
making less confusing, better documented and more compatible with Oracle.
Nevertheless, there are still following incompatibilities with Oracle.
1) We don't insist that there are no format string patterns unmatched to
input string.
2) In FX mode we don't insist space and separators in format string to exactly
match input string.
3) When format string patterns are divided by mix of spaces and separators, we
don't distinguish them, while Oracle takes into account only last group of
spaces/separators.

Make to_timestamp() and to_date() range-check fields of their input.
Historically, something like to_date('2009-06-40','YYYY-MM-DD') would
return '2009-07-10' because there was no prohibition on out-of-range
month or day numbers. This has been widely panned, and it also turns
out that Oracle throws an error in such cases. Since these functions
are nominally Oracle-compatibility features, let's change that.
There's no particular restriction on year (modulo the fact that the
scanner may not believe that more than 4 digits are year digits,
a matter to be addressed separately if at all). But we now check month,
day, hour, minute, second, and fractional-second fields, as well as
day-of-year and second-of-day fields if those are used.
Currently, no checks are made on ISO-8601-style week numbers or day
numbers; it's not very clear what the appropriate rules would be there,
and they're probably so little used that it's not worth sweating over.

Support TZ and OF format codes in to_timestamp().
Formerly, these were only supported in to_char(), but there seems
little reason for that restriction. We should at least have enough
support to permit round-tripping the output of to_char().
In that spirit, TZ accepts either zone abbreviations or numeric
(HH or HH:MM) offsets, which are the cases that to_char() can output.
In an ideal world we'd make it take full zone names too, but
that seems like it'd introduce an unreasonable amount of ambiguity,
since the rules for POSIX-spec zone names are so lax.
OF is a subset of this, accepting only HH or HH:MM.
One small benefit of this improvement is that we can simplify
jsonpath's executeDateTimeMethod function, which no longer needs
to consider the HH and HH:MM cases separately. Moreover, letting
it accept zone abbreviations means it will accept "Z" to mean UTC,
which is emitted by JSON.stringify() for example.

Improve behavior of to_timestamp()/to_date() functions
to_timestamp()/to_date() functions were introduced mainly for Oracle
compatibility, and became very popular among PostgreSQL users. However, some
behavior of to_timestamp()/to_date() functions are both incompatible with Oracle
and confusing for our users. This behavior is related to handling of spaces and
separators in non FX (fixed format) mode. This commit reworks this behavior
making less confusing, better documented and more compatible with Oracle.
Nevertheless, there are still following incompatibilities with Oracle.
1) We don't insist that there are no format string patterns unmatched to
input string.
2) In FX mode we don't insist space and separators in format string to exactly
match input string.
3) When format string patterns are divided by mix of spaces and separators, we
don't distinguish them, while Oracle takes into account only last group of
spaces/separators.

Clean up formatting.c's logic for matching constant strings.
seq_search(), which is used to match input substrings to constants
such as month and day names, had a lot of bizarre and unnecessary
behaviors. It was mostly possible to avert our eyes from that before,
but we don't want to duplicate those behaviors in the upcoming patch
to allow recognition of non-English month and day names. So it's time
to clean this up. In particular:
* seq_search scribbled on the input string, which is a pretty dangerous
thing to do, especially in the badly underdocumented way it was done here.
Fortunately the input string is a temporary copy, but that was being made
three subroutine levels away, making it something easy to break
accidentally. The behavior is externally visible nonetheless, in the form
of odd case-folding in error reports about unrecognized month/day names.
The scribbling is evidently being done to save a few calls to pg_tolower,
but that's such a cheap function (at least for ASCII data) that it's
pretty pointless to worry about. In HEAD I switched it to be
pg_ascii_tolower to ensure it is cheap in all cases; but there are corner
cases in Turkish where this'd change behavior, so leave it as pg_tolower
in the back branches.
* seq_search insisted on knowing the case form (all-upper, all-lower,
or initcap) of the constant strings, so that it didn't have to case-fold
them to perform case-insensitive comparisons. This likewise seems like
excessive micro-optimization, given that pg_tolower is certainly very
cheap for ASCII data. It seems unsafe to assume that we know the case
form that will come out of pg_locale.c for localized month/day names, so
it's better just to define the comparison rule as "downcase all strings
before comparing". (The choice between downcasing and upcasing is
arbitrary so far as English is concerned, but it might not be in other
locales, so follow citext's lead here.)
* seq_search also had a parameter that'd cause it to report a match
after a maximum number of characters, even if the constant string were
longer than that. This was not actually used because no caller passed
a value small enough to cut off a comparison. Replicating that behavior
for localized month/day names seems expensive as well as useless, so
let's get rid of that too.
* from_char_seq_search used the maximum-length parameter to truncate
the input string in error reports about not finding a matching name.
This leads to rather confusing reports in many cases. Worse, it is
outright dangerous if the input string isn't all-ASCII, because we
risk truncating the string in the middle of a multibyte character.
That'd lead either to delivering an illegible error message to the
client, or to encoding-conversion failures that obscure the actual
data problem. Get rid of that in favor of truncating at whitespace
if any (a suggestion due to Alvaro Herrera).
In addition to fixing these things, I const-ified the input string
pointers of DCH_from_char and its subroutines, to make sure there
aren't any other scribbling-on-input problems.
The risk of generating a badly-encoded error message seems like
enough of a bug to justify back-patching, so patch all supported
branches.

ERROR: invalid value "+" for "MON"

Improve behavior of to_timestamp()/to_date() functions
to_timestamp()/to_date() functions were introduced mainly for Oracle
compatibility, and became very popular among PostgreSQL users. However, some
behavior of to_timestamp()/to_date() functions are both incompatible with Oracle
and confusing for our users. This behavior is related to handling of spaces and
separators in non FX (fixed format) mode. This commit reworks this behavior
making less confusing, better documented and more compatible with Oracle.
Nevertheless, there are still following incompatibilities with Oracle.
1) We don't insist that there are no format string patterns unmatched to
input string.
2) In FX mode we don't insist space and separators in format string to exactly
match input string.
3) When format string patterns are divided by mix of spaces and separators, we
don't distinguish them, while Oracle takes into account only last group of
spaces/separators.

Make to_timestamp() and to_date() range-check fields of their input.
Historically, something like to_date('2009-06-40','YYYY-MM-DD') would
return '2009-07-10' because there was no prohibition on out-of-range
month or day numbers. This has been widely panned, and it also turns
out that Oracle throws an error in such cases. Since these functions
are nominally Oracle-compatibility features, let's change that.
There's no particular restriction on year (modulo the fact that the
scanner may not believe that more than 4 digits are year digits,
a matter to be addressed separately if at all). But we now check month,
day, hour, minute, second, and fractional-second fields, as well as
day-of-year and second-of-day fields if those are used.
Currently, no checks are made on ISO-8601-style week numbers or day
numbers; it's not very clear what the appropriate rules would be there,
and they're probably so little used that it's not worth sweating over.

Make to_timestamp() and to_date() range-check fields of their input.
Historically, something like to_date('2009-06-40','YYYY-MM-DD') would
return '2009-07-10' because there was no prohibition on out-of-range
month or day numbers. This has been widely panned, and it also turns
out that Oracle throws an error in such cases. Since these functions
are nominally Oracle-compatibility features, let's change that.
There's no particular restriction on year (modulo the fact that the
scanner may not believe that more than 4 digits are year digits,
a matter to be addressed separately if at all). But we now check month,
day, hour, minute, second, and fractional-second fields, as well as
day-of-year and second-of-day fields if those are used.
Currently, no checks are made on ISO-8601-style week numbers or day
numbers; it's not very clear what the appropriate rules would be there,
and they're probably so little used that it's not worth sweating over.

Support TZ and OF format codes in to_timestamp().
Formerly, these were only supported in to_char(), but there seems
little reason for that restriction. We should at least have enough
support to permit round-tripping the output of to_char().
In that spirit, TZ accepts either zone abbreviations or numeric
(HH or HH:MM) offsets, which are the cases that to_char() can output.
In an ideal world we'd make it take full zone names too, but
that seems like it'd introduce an unreasonable amount of ambiguity,
since the rules for POSIX-spec zone names are so lax.
OF is a subset of this, accepting only HH or HH:MM.
One small benefit of this improvement is that we can simplify
jsonpath's executeDateTimeMethod function, which no longer needs
to consider the HH and HH:MM cases separately. Moreover, letting
it accept zone abbreviations means it will accept "Z" to mean UTC,
which is emitted by JSON.stringify() for example.

Fix some odd behaviors when using a SQL-style simple GMT offset timezone.
Formerly, when using a SQL-spec timezone setting with a fixed GMT offset
(called a "brute force" timezone in the code), the session_timezone
variable was not updated to match the nominal timezone; rather, all code
was expected to ignore session_timezone if HasCTZSet was true. This is
of course obviously fragile, though a search of the code finds only
timeofday() failing to honor the rule. A bigger problem was that
DetermineTimeZoneOffset() supposed that if its pg_tz parameter was
pointer-equal to session_timezone, then HasCTZSet should override the
parameter. This would cause datetime input containing an explicit zone
name to be treated as referencing the brute-force zone instead, if the
zone name happened to match the session timezone that had prevailed
before installing the brute-force zone setting (as reported in bug #8572).
The same malady could affect AT TIME ZONE operators.
To fix, set up session_timezone so that it matches the brute-force zone
specification, which we can do using the POSIX timezone definition syntax
"<abbrev>offset", and get rid of the bogus lookaside check in
DetermineTimeZoneOffset(). Aside from fixing the erroneous behavior in
datetime parsing and AT TIME ZONE, this will cause the timeofday() function
to print its result in the user-requested time zone rather than some
previously-set zone. It might also affect results in third-party
extensions, if there are any that make use of session_timezone without
considering HasCTZSet, but in all cases the new behavior should be saner
than before.
