tcop/postgres.c can use them. Now we have an interlock between
postmaster and postgres.

code cleanup; no major improvements yet.  However, EXPLAIN does produce
more intuitive outputs for nested loops with indexscans now...

without answer. I want continue with to_char(), but I need any answer
for this patch. Please.

Thank! (and sorry of my impatient :-)

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.

	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.

with DEC C.

DEC C doesn't handle double values greater than DBL_MAX, but some
PostgreSQL geo functions assign greater than DBL_MAX values to some vars
in some special cases - that couses SIGFPE. I dunno if that is the only place
to fix to work well with DEC C.

rather than returning a NaN for bogus input to pow().  Namely, HPUX 10.20.
I think this is sufficient evidence for what I thought all along, which
is that the float.c code *must* look at errno whether finite() exists or
not.

equality.  The lobits macro is wrong and extracts the wrong set of
bits out of the structure.

To exhibit the problem:

select '000000:000000'::macaddr = '000000:110000'::macaddr ;

I was able to crash postgres 6.5.3 when I did an 'alter user' command.
After I started a debugger I found the problem in the timezone handling
of
datetime (my Linux box lost its timezone information, that's how the
problem occurred).

Only 7 bytes are reserved for the timezone, without checking for
boundaries.

Attached is a patch that fixes this problem and emits a NOTICE if a
timezone is encountered that is longer than MAXTZLEN bytes, like this:
