Consider interpreting a function call as a trivial (binary-compatible)
type coercion after failing to find an exact match in pg_proc, but before
considering interpretations that involve a function call with one or
more argument type coercions. This avoids surprises wherein what looks
like a type coercion is interpreted as coercing to some third type and
then to the destination type, as in Dave Blasby's bug report of 3-Oct-01.
See subsequent discussion in pghackers.

Attached is a patch which deals with
select 'id' as xxx from table
The issue is:
When the driver gets a data type which does not map into the SQL.Types
it attempts to load the object into a java object. Eventually throwing
an exception indicating that the type "unknown" was not found.
Since the backend defaults "unknown" types to text it was suggested that
the jdbc driver do the same.
This patch does just that.
I have tested it on the above select statement as well as a small
program that serializes, and deserializes a class

AdjustTimestampForTypmod does not work (at least not portably) on
-infinity and +infinity. Put TIMESTAMP_NOT_FINITE guard into the routine,
instead of forgetting it at some call sites. Fixes regression test
failures here.
Implement precision support for timestamp and time, both with and without
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.

Change pg_dump to produce CREATE INDEX commands by using the backend's
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.
Tom Lane [Mon, 1 Oct 2001 20:15:26 +0000 (20:15 +0000)]
Extend pg_get_indexdef() to know about index predicates. Also, tweak
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.

Another round of cleanups for dynahash.c (maybe it's finally clean of
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.

Tweak btree page split logic so that when splitting a page that is
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.
