Subject: [PATCHES] destroydb patch
I am including a patch for destroydb to ask for confirmation before
deleting databases (after I accidentally deleted mine)...destroydb -y
would force delete without any confirmation.
Subject: [PATCHES] memory leak patches in libpq and psql
A couple of small memory leak patches (detected with Purify) primarily
in libpq.
* Fixed (NULL) border problem in psql (run psql, do \m, then select
something from a table...row separators will be nulls)
* Fixed memory leak with the abovementioned border not being freed
properly.
* Fixed memory leak in freePGconn() not freeing conn->port
* Fixed up PQclear() to free parts of PGresult only if these
parts are not null.
* Fixed a decent memory leak that occured after executing every command
in psql. PGresult *results was not freed most of the time.
There is still a leak being detected (2 bytes) in readline functions, but
I think this is old readline library. I will install new one and test it.
Subject: [PATCHES] pqcomprim.c patch
This is the patch by Robert Bruccoleri to fix the endian problem.
(Actually, it's the reverse of his patch. He must have gotten the
order wrong.)
/*
* RelationFlushRelation () below will flush relation information
* from the cache. We must call smgrclose to flush relation
* information from SMGR & FMGR, too. We assume that for temp
* relations smgrunlink is already called by heap_destroyr
* and we skip smgrclose for them. - vadim 05/22/97
*/
smgrclose(reln->rd_rel->relsmgr, reln);
- it avoids memory leaks in SMGR & VFD.
RelationFlushRelation():
there is no more call FileInvalidate(RelationGetSystemPort(relation));
- invalid (FileInvalidate() expects File, not SMGR' fd)
- unuseful anyway.
mdunlink() and mdclose() (too !!!) now free MdfdVec for relation
and add it to free list, so it may be re-used for another relation
later.
2. Fix VFD-manager memory leak (found by Massimo ... and me):
mdunlink() has to call FileUnlink() to free allocation for fileName
and add the Vfd slot to the free list.

- too big number:
strat.h->StrategyEvaluationData->StrategyExpression expression[12]
^^
- so 12 is real max # of strategies, or StrategyEvaluationIsValid
crashes backend (called if CASSER defined).

Subject: [PATCHES] DROP AGGREGATE gram.y typo...
Somehow I dropped a comma in the gram.y part (line 129) of my
patch for drop aggregate. Here's a correct patch for gram.y.
PS. I hope I got the right comma, manually applied :) (scrappy)
Subject: [PATCHES] AIX make patch resubmitted.
Misc patches for AIX from Darren:
1) New src/makefiles/Makefile.aix This patch should only be
applied if the following patch (4) is applied to backend/Makefile!
Still looking into having configure determine the last line to do
the shared link. The 325 code will work for 41, so I put that in
as the default. Included a commented out 41 line for completeness.
*and*
4) Patch the backend Makefile. I've reviewed this patch with respect to the
other ports that use MAKE_EXPORTS (svr4 and univel) as closely as I could
and I don't see where it will break them. If it does, please let me know
and I'll rework it somehow.
Subject: [PATCHES] Re: [PORTS] AIX 6.1 fixes...
Here are the patches for the two things that wouldn't make it thru the AIX
compiler. The geo_ops.c change is harmless I believe. The nbtcompare.c patch
fixes me, but I don't know about any other ports. Maybe wait on that one
until Vadim decides what to do about the unsigned vs signed chars varlena
issue.
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).
