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.

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).
