nodes where it's not really necessary.  In many cases where the scan node
is not the topmost plan node (eg, joins, aggregation), it's possible to
just return the table tuple directly instead of generating an intermediate
projection tuple.  In preliminary testing, this reduced the CPU time
needed for 'SELECT COUNT(*) FROM foo' by about 10%.

Standard says FETCH LAST is after last row, and we don't do that.

either end of subplan results.  This prevents misbehavior of cursors
on SELECT DISTINCT ... queries.  Per bug report 1-Feb-02.

restriction was debatable to begin with, but it has now become obvious
that it breaks forward-porting of user-defined types; contrib/lo being
the most salient example.

definitions on-the-fly, just modify the queries issued by FixupBlobRefs
so that they work even if CREATE CAST hasn't been issued.

connection shutdown.  This is a grotty workaround for a Tcl bug, but
said bug has been there long enough that I'm not holding my breath
for a real fix.  Per discussions and testing from ljb and g.hintermayer.

with some amount of cleanliness.  I see no need to report the internal
Python name rather than the SQL procedure name in error tracebacks.

bison 1.875 and later as we did from earlier bison releases.  Eventually
we will probably want to adopt the newer message spelling ... but not yet.
Per recent discussion on pgpatches.
Note: I didn't change the build rules for bootstrap, ecpg, or plpgsql
grammars, since these do not affect regression test results.

for type 'time without time zone', as we already did for type
'timestamp without time zone'.  This patch was proposed by Tom Lockhart
on 7-Nov-02, but he never got around to applying it.  Adjust regression
tests and documentation to match.

executing a query rewritten by a rule.  Per bug report from Wolfgang Walter.

on strings beginning with '{', but seems best to prevent it going forward.
Per report from Yichen Xie.

(The alternative of increasing the number of digits we are willing to
print looks risky; we might find ourselves printing roundoff garbage.)

to derive non-bogus selectivity for IN clauses.  Further tweaking of
cost estimation for IN.

The code that checks for the 64-bit int type now gives more reasonable
results when cross-compiling: In that case we just take the compiler's
information and trust that the arithmetic works.  Disabling int64 is too
pessimistic.

Try to model the effect of rescanning input tuples in mergejoins;
account for JOIN_IN short-circuiting where appropriate.  Also, recognize
that mergejoin and hashjoin clauses may now be more than single operator
calls, so we have to charge appropriate execution costs.
