a variant of the function for the 'numeric' datatype; it would be possible
to add additional variants for other datatypes, but I haven't done so yet.
This commit includes regression tests and minimal documentation; if we
want developers to actually use this function in applications, we'll
probably need to document what it does more fully.
rather than allowing them only in a few special cases as before. In
particular you can now pass a ROW() construct to a function that accepts
a rowtype parameter. Internal generation of RowExprs fixes a number of
corner cases that used to not work very well, such as referencing the
whole-row result of a JOIN or subquery. This represents a further step in
the work I started a month or so back to make rowtype values into
first-class citizens.

the table. (Possible future improvement: optimize no-op conversions such

Original patch from Rod Taylor, additional work from Tom Lane.
Regression tests and documentation have both been updated.
SQL2003 requires that both ceiling() and ceil() be present, so I have
documented both spellings. SQL2003 doesn't mention pow() as far as I
can see, so I decided to replace pow() with power() in the documentation:
there is little reason to encourage the continued usage of a function
that isn't compliant with the standard, given a standard-compliant
alternative.
RELEASE NOTES: should state that pow() is considered deprecated
(although I don't see the need to ever remove it.)

"millennium" date part implementation in postgresql, both in the code
and the documentation, so that it conforms to the official definition.
If you do not agree with the official definition, please send your
complaint to "pope@vatican.org". I'm not responsible for them;-)
With the previous version, the centuries and millenniums had a wrong
number and started the wrong year. Moreover century number 0, which does
not exist in reality, lasted 200 years. Also, millennium number 0 lasted
2000 years.
If you want postgresql to have it's own definition of "century" and
"millennium" that does not conform to the one of the society, just give
them another name. I would suggest "pgCENTURY" and "pgMILLENNIUM";-)
IMO, if someone may use the options, it means that postgresql is used for
historical data, so it make sense to have an historical definition. Also,
I just want to divide the year by 100 or 1000, I can do that quite easily.

bulletproof defense against crashing due to runaway recursive functions.
remove separate implementation of ALTER TABLE SET WITHOUT OIDS in favor
of doing a regular DROP. Also, cause CREATE TABLE to account completely
correctly for the inheritance status of the OID column. This fixes
problems with dropping OID columns that have dependencies, as noted by
Christopher Kings-Lynne, as well as making sure that you can't drop an
OID column that was inherited from a parent.

A better workaround for the sentence would be something like:

that it's good to join where there are join clauses rather than where there
are not. Also enable it to generate bushy plans at need, so that it doesn't
fail in the presence of multiple IN clauses containing sub-joins. These
changes appear to improve the behavior enough that we can substantially reduce
the default pool size and generations count, thereby decreasing the runtime,
and yet get as good or better plans as we were getting in 7.4. Consequently,
adjust the default GEQO parameters. I also modified the way geqo_effort is
used so that it affects both population size and number of generations;
it's now useful as a single control to adjust the GEQO runtime-vs-plan-quality
tradeoff. Bump geqo_threshold to 12, since even with these changes GEQO
seems to be slower than the regular planner at 11 relations.
default value for geqo_effort is supposed to be 40, not 1. The actual
'genetic' component of the GEQO algorithm has been practically disabled
since 7.1 because of this mistake. Improve documentation while at it.

a) ones that are 100% backward (such as the comment about
outputting this format)
and
b) ones that aren't (such as deprecating the current
postgresql shorthand of
'1Y1M'::interval = 1 year 1 minute

Attached is a patch that addressed all the discussed issues that
did not break backward compatability, including the ability to
output ISO-8601 compliant intervals by setting datestyle to
iso8601basic.
Interval values can now be written as ISO 8601 time intervals, using
the "Format with time-unit designators". This format always starts with
the character 'P', followed by a string of values followed
by single character time-unit designators. A 'T' separates the date and
time parts of the interval.

pghackers proposal of 8-Nov. All the existing cross-type comparison
operators (int2/int4/int8 and float4/float8) have appropriate support.
The original proposal of storing the right-hand-side datatype as part of
the primary key for pg_amop and pg_amproc got modified a bit in the event;
it is easier to store zero as the 'default' case and only store a nonzero
when the operator is actually cross-type. Along the way, remove the
long-since-defunct bigbox_ops operator class.

This prevents creating weird scenarios in which the same privileges
may appear to flow from different sources, and ensures that a superuser
can in fact revoke all privileges if he wants to. In particular this
means that the regression tests work when run by a superuser other than
the original bootstrap userid. Per report from Larry Rosenman.

Attached is a doc patch that does this. The way I've worded it may not
be the best, though.

I suggest adding LOCALTIMESTAMP and LOCALTIME to the first paragraph.
Maybe it should be phrased as:
The following SQL-compatible functions can be used to obtain
current datetime-related values: CURRENT_DATE, CURRENT_TIME,
CURRENT_TIMESTAMP, LOCALTIME and LOCALTIMESTAMP.

before it is de-backslashed, not after. This allows the null string \N
to be reliably distinguished from the data value \N (which must be
represented as \\N). Per bug report from Manfred Koizar ... but it's
amazing this hasn't been reported before ...
Also, be consistent about encoding conversion for null string: the form
specified in the command is in the server encoding, but what is sent
to/from client must be in client encoding. This never worked quite
right before either.
will downcase the supplied field name unless it is double-quoted. Also,
upgrade the routine's handling of double quotes to match the backend,
in particular support doubled double quotes within quoted identifiers.

true but can be set false to avoid problems with forward references,
wrong schema search path, etc. This is just the backend patch, still
need to adjust pg_dump to make use of it.
invalid (has the wrong magic number) until the build is entirely
complete. This turns out to cost no additional writes in the normal
case, since we were rewriting the metapage at the end of the process
anyway. In normal scenarios there's no real gain in security, because
a failed index build would roll back the transaction leaving an unused
index file, but for rebuilding shared system indexes this seems to add
some useful protection.

Attached are two patches:
- installdoc.patch contains an additional paragraph on the win32 console
codepage for the chapter "Installation on Windows"
Due to a lack of SGML-tools, I have only edited the text and not tested
the SGML code - please check it before merging into the CVS branch.
- psqlcodepage.patch adds the warning about a problematic codepage to psql.
