format strings wherever possible. Remarkably, this exercise didn't
turn up any inconsistencies, but it seems a good idea for the future.

'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.

psql's \d option work properly.

In particular, mark all I/O functions that can produce or consume
a date as noncachable, in light of existence of DateStyle variable.

-infinity and +infinity. Put TIMESTAMP_NOT_FINITE guard into the routine,
instead of forgetting it at some call sites. Fixes regression test
failures here.

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.

definition without changing the function's OID, thereby not breaking
rules, views, triggers, etc that depend on it. From Gavin Sherry.

of coping by reducing shared_buffers/max_connections settings.

pg_get_indexdef() function, rather than reaching into the system catalogs
for itself. This eliminates a fair amount of redundant code. Also,
since I just changed pg_get_indexdef() to suppress display of default
index opclasses, this will mean that 7.2 and later dumps will not mention
opclasses unless they are non-default opclasses. Should make life easier
for future index opclass reorganizations.

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.

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).

- Added patch by Christof Petig <christof.petig@wtal.de> to
clean up
ecpglib.

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.

Some compilers are pickier about this than gcc is.

started later. Already-started backends continue to ignore changes

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.

* HOLDER/HOLDERTAB rename to PROCLOCKLINK/PROCLOCKLINKTAG (Bruce)
Will return later.

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.

* HOLDER/HOLDERTAB rename to PROCLOCK/PROCLOCKTAG (Tom)
Didn't use PROCLOCKLINK because it made PROCLOCKLINKTAG too long.

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.

returns a string corresponding to the new setting, not the old,
therefore the previous patch was quite wrong.

SInvalLock. GetSnapshotData(true) has to use exclusive lock, since
it sets MyProc->xmin.
