Bruce Momjian a4d9d3e028 Attached is are a few small fixes for dbmirror.
1. Fixed bug where sequences were being mirrored incorrectly if they
exceeded 127
2. Fixed a bug in the perl script with mirroring sequences(John
Burtenshaw sent an email to patches describing the bug in March but I
htink he forgot to attach his patch)
3. The dates/times in the transaction files will always use 2 digits.

Bruce Momjian 914042fe5f This patch makes the EXECUTE command's completion tag return the
completion tag of the actual statement executed.  This allows the
correct update count to be returned for UPDATE/INSERT/DELETE
statements.

Bruce Momjian ec7c4c1b66 Please find attached a small patch so that "pg_restore" ignores some sql
errors. This is the second submission, which integrates Tom comments about
localisation and exit code. I also added some comments about one sql
command which is not ignored.

Tom Lane 37fa3b6c89 Tweak indexscan and seqscan code to arrange that steps from one page to
the next are handled by ReleaseAndReadBuffer rather than separate
ReleaseBuffer and ReadBuffer calls.  This cuts the number of acquisitions
of the BufMgrLock by a factor of 2 (possibly more, if an indexscan happens
to pull successive rows from the same heap page).  Unfortunately this
doesn't seem enough to get us out of the recently discussed context-switch
storm problem, but it's surely worth doing anyway.

Tom Lane 95a03e9cdf Another round of code cleanup on bufmgr. Use BM_VALID flag to keep track
of whether we have successfully read data into a buffer; this makes the
error behavior a bit more transparent (IMHO anyway), and also makes it
work correctly for local buffers which don't use Start/TerminateBufferIO.
Collapse three separate functions for writing a shared buffer into one.
This overlaps a bit with cleanups that Neil proposed awhile back, but
seems not to have committed yet.

Add CREATE INDEX doc mention of using partial indexes for IS NULL
indexing;  idea from Tom.

Bruce Momjian d1b3915ce1 In reading the 7.4.2 docs, the sql reference page for PREPARE doesn't
reference DEALLOCATE in any way. It points to EXECUTE, but not to
DEALLOCATE. Suggested fix:

... This also means that a single  prepared statement cannot be used by
multiple simultaneous database clients; however, each client can create
their own prepared statement  to use. The prepared statement can be
manually cleaned up using the DEALLOCATE command.

Tom Lane 011c3e62e7 Code review for ARC patch. Eliminate static variables, improve handling
of VACUUM cases so that VACUUM requests don't affect the ARC state at all,
avoid corner case where BufferSync would uselessly rewrite a buffer that
no longer contains the page that was to be flushed.  Make some minor
other cleanups in and around the bufmgr as well, such as moving PinBuffer
and UnpinBuffer into bufmgr.c where they really belong.

Bruce Momjian 31338352bd * Most changes are to fix warnings issued when compiling win32
* removed a few redundant defines
* get_user_name safe under win32
* rationalized pipe read EOF for win32 (UPDATED PATCH USED)
* changed all backend instances of sleep() to pg_usleep

    - except for the SLEEP_ON_ASSERT in assert.c, as it would exceed a
32-bit long [Note to patcher: If a SLEEP_ON_ASSERT of 2000 seconds is
acceptable, please replace with pg_usleep(2000000000L)]

I added a comment to that part of the code:

    /*
     *  It would be nice to use pg_usleep() here, but only does 2000 sec
     *  or 33 minutes, which seems too short.
     */
    sleep(1000000);

Bruce Momjian 862b20b382 Complete TODO item:
o -Allow dump/load of CSV format

This adds new keywords to COPY and \copy:

        CSV - enable CSV mode (comma separated variable)
        QUOTE - specify quote character
        ESCAPE - specify escape character
        FORCE - force quoting of specified column
	LITERAL - suppress null comparison for columns

Doc changes included.  Regression updates coming from Andrew.

Tom Lane b5e52b080c Tweak findTargetlistEntry so that bare names occurring in GROUP BY clauses
are sought first as local FROM columns, then as local SELECT-list aliases,
and finally as outer FROM columns; the former behavior made outer FROM
columns take precedence over aliases.  This does not change spec
conformance because SQL99 allows only the first case anyway, and it seems
more useful and self-consistent.  Per gripe from Dennis Bjorklund 2004-04-05.
