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.

Oh ... didn't know that you did a backpatch. Sorry

bit more helpful by identifying the specific qualified name being
complained of.

coding by Mark Cave-Ayland, some kibitzing by Tom Lane.  initdb forced
due to new column in pg_type.

someone asked me about the FK deadlock fix, mentioned in the 7.3.3
release notes as 3rd change:

     http://www.postgresql.org/docs/current/static/release-7-3-3.html

Actually, that fix was available with 7.4, not 7.3. Don't know if we can
retroactively change the release-notes though.

where signals do not terminate sleep() delays.

Update TODO accordingly.

A better workaround for the sentence would be something like:

        "and it also happens that the user always has permission"

Looks easier to read, I think.

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.

TABLE.  Per recent discussion.

the view pg_stat_activity is missing, as per Bruces suggestion.

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.
