[ Patch comments in three pieces.]

Attached is a pacth against 7.2 which adds locale awareness to the
character classes of the regular expression engine.

I miss that case :-(. Here is the pached patch.

Here is a patch which addresses Tatsuo's concerns (it does return an
static struct instead of constructing it).

src/include/pg_config.h.win32.  Certainly if we have INDEX_MAX_KEYS in
there, we should have FUNC_MAX_ARGS too.

UINT64CONST, since unsigned was what it wanted anyway.  Centralize macro
definitions into c.h.

2) Handle timestamp without time zone.
3) Improve SQLForeignKeys() in multibyte mode.

ALTER COLUMN SET STORAGE should be allowed.

Change elog(ERROR) messages to say that a variable takes one parameter,
 rather than saying that it does not take multiple parameters.

 The last version caught this with an assert because I wasn't sure whether
 we should elog(ERROR) or just loop through the parameters.

 it is now obsolete. Need some regression test cases to prove otherwise...

 These were for cases protected by elog(ERROR) exits, but may as well
 keep the compiler happy. Not sure why they don't show up on my gcc-2.96.x
 version of the compiler.

Update horology-no-DST-before-1970.out (tested on HPUX), plus an extrapolated horology-solaris-1947.out
(needs verification).

 now, but we may want otherwise on systems which support it.

 Use "--enable-integer-datetimes" in configuration to use this rather
 than the original float8 storage. I would recommend the integer-based
 storage for any platform on which it is available. We perhaps should
 make this the default for the production release.
Change timezone(timestamptz) results to return timestamp rather than
 a character string. Formerly, we didn't have a way to represent
 timestamps with an explicit time zone other than freezing the info into
 a string. Now, we can reasonably omit the explicit time zone from the
 result and return a timestamp with values appropriate for the specified
 time zone. Much cleaner, and if you need the time zone in the result
 you can put it into a character string pretty easily anyway.
Allow fractional seconds in date/time types even for dates prior to 1BC.
Limit timestamp data types to 6 decimal places of precision. Just right
 for a micro-second storage of int8 date/time types, and reduces the
 number of places ad-hoc rounding was occuring for the float8-based types.
Use lookup tables for precision/rounding calculations for timestamp and
 interval types.  Formerly used pow() to calculate the desired value but
 with a more limited range there is no reason to not type in a lookup
 table. Should be *much* better performance, though formerly there were
 some optimizations to help minimize the number of times pow() was called.
Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option
 "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED.
Add explicit date/interval operators and functions for addition and
 subtraction. Formerly relied on implicit type promotion from date to
 timestamp with time zone.
Change timezone conversion functions for the timetz type from "timetz()"
 to "timezone()". This is consistant with other time zone coersion
 functions for other types.
Bump the catalog version to 200204201.
Fix up regression tests to reflect changes in fractional seconds
 representation for date/times in BC eras.
All regression tests pass on my Linux box.

 This is a big change from past behavior, but the last release was
 designed to handle this correctly for dump/restore upgrades.
Fix up handling of SET value arguments. Allow lists for most options at
 least at the parser level; multiple values may be rejected at the
 command processor of course.
Allow more variations on values for SET commands, including integer and
 float values where formerly stringy fields were required.
Check precision specification for date/time fields against the true
 precision range allowed by the data types. Especially useful with the
 new int8-based storage for these types, where precision is fixed and
 predictable.
Stub out a basic CREATE ASSERTION per SQL9x. Does not do anything (yet) but
 should be augmented as appropriate.
Minor fixups in braces and tabbing.

 most required a stringy syntax in the parser; now integers and floats
 can (or should) be handled. There is at least one cheesy error message
 mentioning sending mail to me if there are problems; should be changed
 prior to release.
Allow lists of values from the parser in more cases. If multiple arguments
 were not allowed previously, they probably are not allowed now, but at
 least the data structures being passed around are more consistant across
 more cases.

 compiled for integer date/time storage and to check the length of
 storage for the locale fields in the same data structure.
Slightly reword some of the error messages to be more accurate on
 possible recovery options (e.g. recompile *or* re-initdb).
Bump version number on this file.

 capabilities of specifying time zones as intervals per SQL9x.
Put refentrytitle contents on the same line as the tag.
 Otherwise, leading whitespace is propagated into the product, which
 (at least) messes up the ToC layout.
Remove (some) docinfo tags containing dates. Best to omit if the dates
 are not accurate; maybe use CVS dates instead or leave them out.

different privilege bits (might as well make use of the space we were
wasting on padding).  EXECUTE and USAGE bits for procedures, languages
now are separate privileges instead of being overlaid on SELECT.  Add
privileges for namespaces and databases.  The GRANT and REVOKE commands
work for these object types, but we don't actually enforce the privileges
yet...

Use flex flags -CF.  Pass the to-be-scanned string around as StringInfo
type, to avoid querying the length repeatedly.  Clean up some code and
remove lex-compatibility cruft.  Escape backslash sequences inline.  Use
flex-provided yy_scan_buffer() function to set up input, rather than using
myinput().

_RETURN now, since there's no need to keep 'em unique anymore.

(tgrelid, tgname).  This provides an additional check on trigger name
uniqueness per-table (which was already enforced by the code anyway).
With this change, RelationBuildTriggers will read the triggers in
order by tgname, since it's scanning using this index.  Since a
predictable trigger ordering has been requested for some time, document
this behavior as a feature.  Also document that rules fire in name
order, since yesterday's changes to pg_rewrite indexing cause that too.

per previous discussion.
