a6020b396b I've just finished the Chinese NLS support(zh_CN part) files
translation,
    the attachement is those four files.
   (.tar.gz file, with the directory, root is $PGSRC).
    Tested on some Linux platform.

720ca220a9 Attached please find an initiation of the
NLS effort for the 'postgresql' component.
It includes 'ru.po', which should be added
to /src/backend/po/ and a typical patch for
nls.mk with the 'ru' entry added in
the AVAIL_LANGUAGES.

I'll submit a patch with more translations
for pg_dump once CVSweb becomes available.
CVSweb for me right now is the only way
to get to the source code until my system
is completely setup by the end of the week.

fcd2e372a7 Consistently use gcc's __attribute__((format)) to check sprintf-style
format strings wherever possible.  Remarkably, this exercise didn't
turn up any inconsistencies, but it seems a good idea for the future.

2e5fda7b7e DROP AGGREGATE and COMMENT ON AGGREGATE now accept the expected syntax
'aggname (aggtype)'.  The old syntax 'aggname aggtype' is still accepted
for backwards compatibility.  Fix pg_dump, which was actually broken for
most cases of user-defined aggregates.  Clean up error messages associated
with these commands.

5c35b5973b Teach format_type about time/timestamp precision, so that pg_dump and

77be5f9451 AdjustTimestampForTypmod does not work (at least not portably) on
-infinity and +infinity.  Put TIMESTAMP_NOT_FINITE guard into the routine,
instead of forgetting it at some call sites.  Fixes regression test
failures here.

3e1beda2cd Implement precision support for timestamp and time, both with and without
time zones.
SQL99 spec requires a default of zero (round to seconds) which is set
 in gram.y as typmod is set in the parse tree. We *could* change to a
 default of either 6 (for internal compatibility with previous versions)
 or 2 (for external compatibility with previous versions).
Evaluate entries in pg_proc wrt the iscachable attribute for timestamp and
 other date/time types. Try to recognize cases where side effects like the
 current time zone setting may have an effect on results to decide whether
 something is cachable or not.

f2c657375d Add CREATE OR REPLACE FUNCTION syntax to allow replacing a function
definition without changing the function's OID, thereby not breaking
rules, views, triggers, etc that depend on it.  From Gavin Sherry.

e5bbf19659 Extend pg_get_indexdef() to know about index predicates. Also, tweak
it to suppress index opclass output for opclasses that are the default
for their datatype; only non-default opclasses are shown explicitly.
This is expected to improve portability of the CREATE INDEX command
across future versions of Postgres --- we've changed index opclasses
too often in the past to think we won't do so again.

87fd2dbe7c Clean up a little more carefully around fork of pgstat subprocess.
Partial support for BEOS (not sure whether second fork of grandchild
process needs these extra calls or not; someone who has BEOS will need
to test it).

5999e78fc4 Another round of cleanups for dynahash.c (maybe it's finally clean of
portability issues).  Caller-visible data structures are now allocated
on MAXALIGN boundaries, allowing safe use of datatypes wider than 'long'.
Rejigger hash_create API so that caller specifies size of key and
total size of entry, not size of key and size of rest of entry.
This simplifies life considerably since each number is just a sizeof(),
and padding issues etc. are taken care of automatically.

f00da6d841 Allow the postmaster to accept changes in PGC_BACKEND GUC variables
from the config file, so that these changes will propagate to backends
started later.  Already-started backends continue to ignore changes
in these variables.

f9f258281e Create a GUC parameter max_files_per_process that is a configurable
upper limit on what we will believe from sysconf(_SC_OPEN_MAX).  The
default value is 1000, so that under ordinary conditions it won't
affect the behavior.  But on platforms where the kernel promises far
more than it can deliver, this can be used to prevent running out of
file descriptors.  See numerous past discussions, eg, pgsql-hackers
around 23-Dec-2000.

0386ccfed1 Back out change. Too many place to change too close to beta:

1663f33838 Tweak btree page split logic so that when splitting a page that is
rightmost on its tree level, we split 2/3 to the left and 1/3 to the
new right page, rather than the even split we use elsewhere.  The idea
is that when faced with a steadily increasing series of inserted keys
(such as sequence or timestamp values), we'll end up with a btree that's
about 2/3ds full not 1/2 full, which is much closer to the desired
steady-state load for a btree.  Per suggestion from Ann Harrison of
IBPhoenix.

8ca61476e0 Cope with the likelihood that setlocale and localeconv will return
pointers to data that will be changed by any later call to setlocale.
Must copy what they return to be sure we get the right answer.

2a314add00 Whoops, I was a tad too enthusiastic about using shared lock mode for
SInvalLock.  GetSnapshotData(true) has to use exclusive lock, since
it sets MyProc->xmin.

499abb0c0f Implement new 'lightweight lock manager' that's intermediate between
existing lock manager and spinlocks: it understands exclusive vs shared
lock but has few other fancy features.  Replace most uses of spinlocks
with lightweight locks.  All remaining uses of spinlocks have very short
lock hold times (a few dozen instructions), so tweak spinlock backoff
code to work efficiently given this assumption.  All per my proposal on
pghackers 26-Sep-01.

818fb55ac4 I have made three changes to the rtree code: one bug fix and
two performance improvements.  I put an explanation of the
changes at

http://cs1.cs.nyu.edu/been/postgres-rtree.html

The performance improvements are quite significant.

All the changes are in the file src/backend/access/rtree/rtree.c

I was working with the 7.1.3 code.

I'm including the diff output as an attachment.

6f58115ddd Measure the current transaction time to milliseconds.
Define a new function, GetCurrentTransactionStartTimeUsec() to get the time
 to this precision.
Allow now() and timestamp 'now' to use this higher precision result so
 we now have fractional seconds in this "constant".
Add timestamp without time zone type.
Move previous timestamp type to timestamp with time zone.
Accept another ISO variant for date/time values: yyyy-mm-ddThh:mm:ss
 (note the "T" separating the day from hours information).
Remove 'current' from date/time types; convert to 'now' in input.
Separate time and timetz regression tests.
Separate timestamp and timestamptz regression test.

d435592f33 Repair oversight in recent changes to index-creation: tuple time qual
check *can* return HEAPTUPLE_INSERT_IN_PROGRESS or HEAPTUPLE_DELETE_IN_PROGRESS,
even though we have ShareLock on the relation.  To wit, this can happen
if the tuple was inserted/deleted by our own transaction.  Per report from
Justin Clift 9/23.

1481b3b28b Remove useless test for time field in pg_control being > 0. We don't
need this, and it will create a Y2038 failure.  Per report from David
Wheeler, who is evidently running on a platform where time_t is already
negative.
