All of these tests have been completely inspected and give correct results.

1) datetime_pl_span() added the seconds field before adding the months
field. This lead to erroneous results for e.g.
select datetime '1999-11-30' + timespan '1 mon - 1 sec';
Reverse the order of operations to add months first.
2) tm2timespan() did all intermediate math as integer, converting to double
at the very end. This resulted in hidden overflows when given very large
integer days, hours, etc. For example,
select '74565 days'::timespan;
produced the wrong result. Change code to ensure that doubles are used
for intermediate calculations.

during InitProcessingMode and the CurrentTransactionState was neither
TRANS_DEFAULT nor TRANS_DISABLED. Unfortunately, after someone's recent
change to start the transaction manager earlier in startup than it used
to be started, that caused an abort() and consequent database system
reset on quite harmless errors (such as rejecting an invalid user name!).
As far as I can see, the test on CurrentTransactionState was completely
useless anyway, so I've removed it.

relcache entry no longer leaks a small amount of memory. index_endscan
now releases all the memory acquired by index_beginscan, so callers of it
should NOT pfree the scan descriptor anymore.

This is the patch for the final bit. Sorry that it's separate.

I finally got around to schlepping through pg_dump, to finish what I started
about three months (or more) ago. Attached is a gzipped diff file to apply
in the bin/pg_dump directory. This should remove all string length
dependencies, except one, which I'm working on. It has been through some
rudimentary unit testing, but that's about it, so if any of you would give
it a more strenuous run-through, I'd be grateful for the feedback.
Cheers...

not BLCKSZ/2 as some of us thought. Add check for oversize item so that
failure is detected before corrupting the index, not after.

SELECT null::text;
SELECT int4fac(null);
work as expected now. In some cases a NULL must be surrounded by
parentheses:
SELECT 2 + null; fails
SELECT 2 + (null); OK
This is a grammatical ambiguity that seems difficult to avoid. Other
than that, NULLs seem to behave about like you'd expect. The internal
implementation is that NULL constants are typed as UNKNOWN (like
untyped string constants) until the parser can deduce the right type.

Locate path of postmaster in a portable way (stolen from initdb)
Add postmaster.opts.default.sample which should be copied into
$PGLIB in the installtion process. Also, it will be installed into
$PGDATA while initdb is running.
