This changes the data type of the catalog fields datcollate, datctype,
collcollate, and collctype from name to text. There wasn't ever a
really good reason for them to be of type name; presumably this was
just carried over from when they were fixed-size fields in pg_control,
first into the corresponding pg_database fields, and then to
pg_collation. The values are not identifiers or object names, and we
don't ever look them up that way.
Changing to type text saves space in the typical case, since locale
names are typically only a few bytes long. But it is also possible
that an ICU locale name with several customization options appended
could be longer than 63 bytes, so this also enables that case, which
was previously probably broken.

Previously, callers of pg_newlocale_from_collation() did not call it
if the collation was DEFAULT_COLLATION_OID and instead proceeded with
a pg_locale_t of 0. Instead, now we call it anyway and have it return
0 if the default collation was passed. It already did this, so we
just have to adjust the callers. This simplifies all the call sites
and also makes future enhancements easier.
After discussion and testing, the previous comment in pg_locale.c
about avoiding this for performance reasons may have been mistaken
since it was testing a very different patch version way back when.

Since at least 2001 we've used putenv() and avoided setenv(), on the
grounds that the latter was unportable and not in POSIX. However,
POSIX added it that same year, and by now the situation has reversed:
setenv() is probably more portable than putenv(), since POSIX now
treats the latter as not being a core function. And setenv() has
cleaner semantics too. So, let's reverse that old policy.
This commit adds a simple src/port/ implementation of setenv() for
any stragglers (we have one in the buildfarm, but I'd not be surprised
if that code is never used in the field). More importantly, extend
win32env.c to also support setenv(). Then, replace usages of putenv()
with setenv(), and get rid of some ad-hoc implementations of setenv()
wannabees.
Also, adjust our src/port/ implementation of unsetenv() to follow the
POSIX spec that it returns an error indicator, rather than returning
void as per the ancient BSD convention. I don't feel a need to make
all the call sites check for errors, but the portability stub ought
to match real-world practice.

Invent a new flag bit HASH_STRINGS to specify C-string hashing, which
was formerly the default; and add assertions insisting that exactly
one of the bits HASH_STRINGS, HASH_BLOBS, and HASH_FUNCTION be set.
This is in hopes of preventing recurrences of the type of oversight
fixed in commit a1b8aa1e4 (i.e., mistakenly omitting HASH_BLOBS).
Also, when HASH_STRINGS is specified, insist that the keysize be
more than 8 bytes. This is a heuristic, but it should catch
accidental use of HASH_STRINGS for integer or pointer keys.
(Nearly all existing use-cases set the keysize to NAMEDATALEN or
more, so there's little reason to think this restriction should
be problematic.)
Tweak hash_create() to insist that the HASH_ELEM flag be set, and
remove the defaults it had for keysize and entrysize. Since those
defaults were undocumented and basically useless, no callers
omitted HASH_ELEM anyway.
Also, remove memset's zeroing the HASHCTL parameter struct from
those callers that had one. This has never been really necessary,
and while it wasn't a bad coding convention it was confusing that
some callers did it and some did not. We might as well save a few
cycles by standardizing on "not".
Also improve the documentation for hash_create().
In passing, improve reinit.c's usage of a hash table by storing
the key as a binary Oid rather than a string; and, since that's
a temporary hash table, allocate it in CurrentMemoryContext for
neatness.

Buildfarm members that lack both HAVE_LOCALE_T and USE_ICU have been
complaining about pg_newlocale_from_collation's collcollate variable.
This is evidently fallout from commit 7d1297df0, which removed the
only usage outside those two #ifdef'd code paths. Mark the variable
pg_attribute_unused(), like its sibling collctype, which has been that
way for a long time.
Commit 257836a7 included an assertion that a version lookup routine is
not trying to look up "C" or "POSIX", but that case is reachable with
the user-facing SQL function pg_collation_actual_version(). Remove the
assertion.
Accept that we can't get versions for such locale names for now. Users
will need to specify the newer language tag format to enable the
collation versioning feature. It's not clear that we can do automatic
conversion from the old style to the new style reliably enough for this
purpose.
Unfortunately, this means that collation versioning probably won't work
for the default collation unless you provide something like en-US at
initdb or CREATE DATABASE time (though, for reasons not yet understood,
it does seem to work on some systems). It'd be nice to find a better
solution, or document this quirk if we settle on it, but this should
unbreak the 3 failing build farm animals in the meantime.

had no effect in input format strings. Now it does. to_date()

that to_char() would output for the same format code. Matching is
case-insensitive (per the active collation's notion of what that

cache_locale_time (extraction of LC_TIME-related info) had never been
taught the lessons we previously learned about extraction of info related
to LC_MONETARY and LC_NUMERIC. Specifically, commit 95a777c61 taught
PGLC_localeconv() that data coming out of localeconv() was in an encoding
determined by the relevant locale, but we didn't realize that there's a
similar issue with strftime(). And commit a4930e7ca hardened
PGLC_localeconv() against errors occurring partway through, but failed
to do likewise for cache_locale_time(). So, rearrange the latter
function to perform encoding conversion and not risk failure while
it's got the locales set to temporary values.
This time around I also changed PGLC_localeconv() to treat it as FATAL
if it can't restore the previous settings of the locale values. There
is no reason (except possibly OOM) for that to fail, and proceeding with
the wrong locale values seems like a seriously bad idea --- especially
on Windows where we have to also temporarily change LC_CTYPE. Also,
protect against the possibility that we can't identify the codeset
reported for LC_MONETARY or LC_NUMERIC; rather than just failing,
try to validate the data without conversion.
The user-visible symptom this fixes is that if LC_TIME is set to a locale
name that implies an encoding different from the database encoding,
non-ASCII localized day and month names would be retrieved in the wrong
encoding, leading to either unexpected encoding-conversion error reports
or wrong output from to_char(). The other possible failure modes are
unlikely enough that we've not seen reports of them, AFAIK.
The encoding conversion problems do not manifest on Windows, since
we'd already created special-case code to handle that issue there.

This adds a flag "deterministic" to collations. If that is false,
such a collation disables various optimizations that assume that
strings are equal only if they are byte-wise equal. That then allows
use cases such as case-insensitive or accent-insensitive comparisons
or handling of strings with different Unicode normal forms.
This functionality is only supported with the ICU provider. At least
glibc doesn't appear to have any locales that work in a
nondeterministic way, so it's not worth supporting this for the libc
provider.
The term "deterministic comparison" in this context is from Unicode
Technical Standard #10
(https://unicode.org/reports/tr10/#Deterministic_Comparison).
This patch makes changes in three areas:
- CREATE COLLATION DDL changes and system catalog changes to support
this new flag.
- Many executor nodes and auxiliary code are extended to track
collations. Previously, this code would just throw away collation
information, because the eventually-called user-defined functions
didn't use it since they only cared about equality, which didn't
need collation information.
- String data type functions that do equality comparisons and hashing
are changed to take the (non-)deterministic flag into account. For
comparison, this just means skipping various shortcuts and tie
breakers that use byte-wise comparison. For hashing, we first need
to convert the input string to a canonical "sort key" using the ICU
analogue of strxfrm().

Unrecognized attribute names are supposed to be ignored. But the code
would error out on an unrecognized attribute value even if it did not
recognize the attribute name. So unrecognized attributes wouldn't
really be ignored unless the value happened to be one that matched a
recognized value. This would break some important cases where the
attribute would be processed by ucol_open() directly. Fix that and
add a test case.
The restructured code should also avoid compiler warnings about
initializing a UColAttribute value to -1, because the type might be an
unsigned enum. (reported by Andres Freund)
Starting in ICU 54, collation customization attributes can be
specified in the locale string, for example
"@colStrength=primary;colCaseLevel=yes". Add support for this for
older ICU versions as well, by adding some minimal parsing of the
attributes in the locale string and calling ucol_setAttribute() on
them. This is essentially what never ICU versions do internally in
ucol_open(). This was we can offer this functionality in a consistent
way in all ICU versions supported by PostgreSQL.

pg_newlocale_from_collation() used malloc() and strdup() directly,
which is generally not per backend coding style, and it didn't bother
to check for failure results, but would just SIGSEGV instead. Also,
if one of the numerous error checks in the middle of the function
failed, the already-allocated memory would be leaked permanently.
Admittedly, it's not a lot of memory, but it could build up if this
function were called repeatedly for a bad collation.
The first two problems are easily cured by palloc'ing in TopMemoryContext
instead of calling libc directly. We can fairly easily dodge the leakage
problem for the struct pg_locale_struct by filling in a temporary variable
and allocating permanent storage only once we reach the bottom of the
function. It's harder to get rid of the potential leakage for ICU's copy
of the collcollate string, but at least that's only allocated after most
of the error checks; so live with that aspect.
Back-patch to v10 where this code came in, with one or another of the
ICU patches.
The early buildfarm returns for commit 1e165d05f are pretty awful:
not only does Windows not return a useful error, but it looks like
a lot of Unix-ish platforms don't either. Given the number of
different errnos seen so far, guess that what's really going on is
that some newlocale() implementations fail to set errno at all.
Hence, let's try zeroing errno just before newlocale() and then
if it's still zero report as though it's ENOENT. That should cover
the Windows case too.
It's clear that we'll have to drop the regression test case, unless
we want to maintain a separate expected-file for platforms without
HAVE_LOCALE_T. But I'll leave it there awhile longer to see if this
actually improves matters or not.

The simple calculations done to estimate the size of the output buffers
for ucnv_fromUChars() and ucnv_toUChars() could overflow int32_t for
large strings. To avoid that, go the long way and run the function
first without an output buffer to get the correct output buffer size
requirement.
ICU does not support "collate" and "ctype" being different, so the
collctype catalog column is ignored. But for catalog neatness, ensure
that they are the same.
Callers of icu_to_uchar() neglected to pfree the result string when done
with it. This results in catastrophic memory leaks in varstr_cmp(),
because of our prevailing assumption that btree comparison functions don't
leak memory. For safety, make all the call sites clean up leaks, though
I suspect that we could get away without it in formatting.c. I audited
callers of icu_from_uchar() as well, but found no places that seemed to
have a comparable issue.
Add function API specifications for icu_to_uchar() and icu_from_uchar();
the lack of any thought-through specification is perhaps not unrelated
to the existence of this bug in the first place. Fix icu_to_uchar()
to guarantee a nul-terminated result; although no existing caller appears
to care, the fact that it would have been nul-terminated except in
extreme corner cases seems ideally designed to bite someone on the rear
someday. Fix ucnv_fromUChars() destCapacity argument --- in the worst
case, that could perhaps have led to a non-nul-terminated result, too.
Fix icu_from_uchar() to have a more reasonable definition of the function
result --- no callers are actually paying attention, so this isn't a live
bug, but it's certainly sloppily designed. Const-ify icu_from_uchar()'s
input string for consistency.
That is not the end of what needs to be done to these functions, but

Don't move parenthesized lines to the left, even if that means they
flow past the right margin.
By default, BSD indent lines up statement continuation lines that are
within parentheses so that they start just to the right of the preceding
left parenthesis. However, traditionally, if that resulted in the
continuation line extending to the right of the desired right margin,
then indent would push it left just far enough to not overrun the margin,
if it could do so without making the continuation line start to the left of
the current statement indent. That makes for a weird mix of indentations
unless one has been completely rigid about never violating the 80-column
limit.
This behavior has been pretty universally panned by Postgres developers.
Hence, disable it with indent's new -lpl switch, so that parenthesized
lines are always lined up with the preceding left paren.
This patch is much less interesting than the first round of indent
changes, but also bulkier, so I thought it best to separate the effects.

Change pg_bsd_indent to follow upstream rules for placement of comments
to the right of code, and remove pgindent hack that caused comments
following #endif to not obey the general rule.
Commit e3860ffa4d wasn't actually using
the published version of pg_bsd_indent, but a hacked-up version that
tried to minimize the amount of movement of comments to the right of
code. The situation of interest is where such a comment has to be
moved to the right of its default placement at column 33 because there's
code there. BSD indent has always moved right in units of tab stops
in such cases --- but in the previous incarnation, indent was working
in 8-space tab stops, while now it knows we use 4-space tabs. So the
net result is that in about half the cases, such comments are placed
one tab stop left of before. This is better all around: it leaves
more room on the line for comment text, and it means that in such
cases the comment uniformly starts at the next 4-space tab stop after
the code, rather than sometimes one and sometimes two tabs after.
Also, ensure that comments following #endif are indented the same
as comments following other preprocessor commands such as #else.
That inconsistency turns out to have been self-inflicted damage
from a poorly-thought-through post-indent "fixup" in pgindent.

The new indent version includes numerous fixes thanks to Piotr Stefaniak.
The main changes visible in this commit are:
* Nicer formatting of function-pointer declarations.
* No longer unexpectedly removes spaces in expressions using casts,
sizeof, or offsetof.
* No longer wants to add a space in "struct structname *varname", as
well as some similar cases for const- or volatile-qualified pointers.
* Declarations using PG_USED_FOR_ASSERTS_ONLY are formatted more nicely.
* Fixes bug where comments following declarations were sometimes placed
with no space separating them from the code.
* Fixes some odd decisions for comments following case labels.
* Fixes some cases where comments following code were indented to less
than the expected column 33.
On the less good side, it now tends to put more whitespace around typedef
names that are not listed in typedefs.list. This might encourage us to
put more effort into typedef name collection; it's not really a bug in
indent itself.
There are more changes coming after this round, having to do with comment
indentation and alignment of lines appearing within parentheses. I wanted
to limit the size of the diffs to something that could be reviewed without
one's eyes completely glazing over, so it seemed better to split up the
changes as much as practical.
