This commit teaches ANALYZE to store such stats in pg_statistic, but
nothing is done yet about teaching the planner to use 'em.
Also, repair longstanding oversight in separate ANALYZE command: it
updated the pg_class.relpages and reltuples counts for the table proper,
but not for indexes.

vs. timestamptz.  This allows use of indexes for expressions like
  datecol >= date 'today' - interval '1 month'
which were formerly not indexable without casting the righthand side
down from timestamp to date.

Nov 2002: when constant-expression simplification removes all the
aggregate function calls from a query, that doesn't mean we can act as
though there never were any aggregates.  Per bug report from Gabor Szucs.

indexes, it seems like we ought to put another layer of indirection
between the compute_stats functions and the actual data storage.  This
would allow us to compute the values on-the-fly, for example.

for already empty buffers because their buffer tag was not cleard out
when the buffers have been invalidated before.

Also removed the misnamed BM_FREE bufhdr flag and replaced the checks,
which effectively ask if the buffer is unpinned, with checks against the
refcount field.

wit: Add a header record to each WAL segment file so that it can be reliably
identified.  Avoid splitting WAL records across segment files (this is not
strictly necessary, but makes it simpler to incorporate the header records).
Make WAL entries for file creation, deletion, and truncation (as foreseen but
never implemented by Vadim).  Also, add support for making XLOG_SEG_SIZE
configurable at compile time, similarly to BLCKSZ.  Fix a couple bugs I
introduced in WAL replay during recent smgr API changes.  initdb is forced
due to changes in pg_control contents.

allow the bgwriter to start before the startup subprocess has finished
... it tends to crash otherwise.  (The same problem may have existed for
the checkpointer, I'm not entirely sure.)  Remove some code that was
redundant because the bgwriter is handled as a member of the backend list.

Remove thread locking for non-thread-safe functions, instead throw a
compile error.

Platforms will have to re-run tools/thread to record their thread
safety.

Without this patch, no thread locking or *_r functions were being used.

vacuum cost-based-delay patch to apply to VACUUM FULL, ANALYZE, and
non-btree index vacuuming.

By the way, where is the documentation for the cost-based-delay patch?

the relcache, and so the notion of 'blind write' is gone.  This should
improve efficiency in bgwriter and background checkpoint processes.
Internal restructuring in md.c to remove the not-very-useful array of
MdfdVec objects --- might as well just use pointers.
Also remove the long-dead 'persistent main memory' storage manager (mm.c),
since it seems quite unlikely to ever get resurrected.

Natoli and Bruce Momjian (and some cosmetic fixes from Neil Conway).
Changes:

    - remove duplicate signal definitions from pqsignal.h

    - replace pqkill() with kill() and redefine kill() in Win32

    - use ereport() in place of fprintf() in some error handling in
      pqsignal.c

    - export pg_queue_signal() and make use of it where necessary

    - add a console control handler for Ctrl-C and similar handling
      on Win32

    - do WaitForSingleObjectEx() in CHECK_FOR_INTERRUPTS() on Win32;
      query cancelling should now work on Win32

    - various other fixes and cleanups

is asked to assign a variable to itself, it will result in doing a
memcpy() on an entirely-overlapping memory range, which results in
undefined behavior according to ANSI C. That said, it is unlikely to
actually do anything bad on any sane libc, but this keeps valgrind quiet.

Make btree index creation and initial validation of foreign-key constraints
use maintenance_work_mem rather than work_mem as their memory limit.
Add some code to guc.c to allow these variables to be referenced by their
old names in SHOW and SET commands, for backwards compatibility.

committed separately.

Fixed.

report and patch from Dennis Bjorkland, some cleanup by Andrew Dunstan,
and finally some editorializing from Neil Conway.
