all local buffers @ xact commit, so accordingly nextFreeLocalBuf
is first local buffer now.
It helps to avoid unnecessary local buffer allocations in LocalBufferAlloc()
latter ("memmory leaks" in 'order by').
2. ResetLocalBufferPool() lost allocated local buffers:
memset(LocalBufferDescriptors, 0, sizeof(BufferDesc) * NLocBuffer);
(local buffers leak @ xact aborts).
Bring optional new-storage date and time up to date and test.
This new storage format should fix the "Sparc gcc -O2 bug".
(Enable new code with USE_NEW_DATE and USE_NEW_TIME in dt.h)
Add type conversion functions for floating point numbers.
Check for zero in unary minus floating point code (IEEE allows an
explicit negative zero which looks ugly in a query result!).
Ensure circle type has non-negative radius.

Fix: keys ordering stuff moved to _bt_first().

Subject: [HACKERS] Inputting money
I notice that I have to put single quotes around money amounts if there
is a decimal point in the value. I appears to be happening because there
is something changing things like "123.45" to "123.450000" and the code
has a problem with that. There may be a better way to fix this but here
is a simple change to cash.c that lets it accept trailing zeroes.
Add comparison operators to boolean and smaller/larger operators to datetime
and timespan. Fix int4 overflow math problem in timespan comparison operators.
Here are patches which should help fix timezone problems in the
datetime and abstime code. Also, I repatched varlena.c to add in
some comments and a little error checking on top of Vadim's earlier
repairs. There are slight mods to the circle data type to have the
distance operator between circles measure the distance between
closest points rather than between centers.
Subject: [PATCHES] Patches for compiling 6.1 on Digital Unix 3.2c
Attached to this message are the patches I needed to compile 6.1 cleanly
under Digital Unix 3.2c with DEC cc.
I hope these are the last ones. At least, the number of files needing a
patch has decreased noticeably since I sent my previous patches. Nice work
:-)
One of the patches is a bug fix, but I'm including it here anyway.
With these patches applied, the beast seems to work properly. However,
I've done only some preliminary tests. More on this later (but hopefully
before the April 30 deadline... :-)
postgres backend processes end up as so called zombies. It seems that
only Linux a.out (libc.4.6.27) systems are affected.

nestloop's join clauses doesn't work in some cases:
* 1. fix_indxqual_references may change varattno-s in
* inner_indxqual;
* 2. clauses may be commuted
