Privent shrinking if there are tuples modifyed by running transactions

Subject: [PATCHES] patch for a memory leak
Well...I screwed up and posted the wrong patch for psql originally..
The patch for that patch wposted below will fix it..
Subject: [PATCHES] Another destroydb patch
This is a patch to my previous destroydb patch cause some people wanted
slightly different behavior. After this patch is applied, destroydb
will destroy a database as usual, but if added -i flag (which could be
aliased like rm -i) would ask for confirmation.
Subject: [PATCHES] pg_dump memory leak patch
This patch fixes a HUGE memory leak problem in pg_dump.
Pretty much anything that was allocated was never freed and Purify
reported about 40% possible memory leak and 6% actual leak. I added
functions to clear out all the allocated structures. After the patch
Purify returns 0 for number of bytes leaked...
Subject: [PATCHES] psql - \dt,\di commands.
I sent this a couple of months ago in re a request by Maxim
Kozin, but I had the patch reversed, creating some confusion
over applying it.
Here's a more complete version.
Adds \dt to list only tables/views and \di to list only
indicies. \d will still work as before.
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

*/
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.

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).
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)
Subject: [PORTS] minor fix for DGUX port
src/include/port/dgux.h needs the following three lines appended:
#ifndef BYTE_ORDER
#define BYTE_ORDER BIG_ENDIAN
#endif
I believe this to be correct for DG/UX on M88k processors. I don't have one of
the new Intel-based boxes to check on.
Include some additional path functions which were coded but omitted here.
Add translation and rotation/scaling operators for some geometric types.
Fix bugs in some geometry comparison operator declarations.
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.
Subject: [PATCHES] libpq patch
Hi,
here is a small patch which fixes two problems:
1. libpq/libpq-fe.h:
somehow disappeared the line
#define DefaultOption ""
now compilation stops with an error complainig an
unknown DefaultOption (970508).
2. Same patch as I sent already twice, but it never made it
into the source tree: there is no default value for
AuthType and Password. This way any libpq-application
(i.e. perl-scripts) which use the function PQconnectdb
will break with PostgreSQL-6.1. The patch simply uses
an empty string as default value.
Subject: [PATCHES] Patches for boolean, timespan and reltime regression tests.
Hi All,
Here are a couple of patches to the regression tests to introduce
some specific ordering to the results.
I've only made changes to the queries that were exhibiting differences
on my regression runs.
This will also have the side effect of testing the ordering code for
the boolean and some of the time types.
Subject: [PATCHES] libpq SET var TO patch
One last, I hope. This one corrects a bogus format string, and
actually sends the contents of PG_DATESTYLE to the backend. That
means, you can do a setenv PG_DATESTYLE 'iso', and your libpq
will pick that up and tell the backend.
Subject: [PATCHES] port patch: ultrix4
ultrix4 doesn't compile without this. this also fixes a problem
with dynamic loading (ultrix relocatable objects must be loaded
with -G 0).
Subject: [PATCHES] Three small patches.
Hi,
Here are 3 small patches to the postgreSQL source sup'd on
the 6th May 1997.
The 1st 2 fix the shell backslash "c" handling used to suppress
the newline on some unix shells. (The \c needs to be inside quote.)
The 3rd may or may not be the correct way to fix the missing
define of INDEX_MAX_KEYS in pg_dump.h
fd = FileNameOpenFile(path, O_RDWR|O_CREAT|O_EXCL, 0600);
/*
* If the file already exists and is empty, we pretend that the
* create succeeded. During bootstrap processing, we skip that check,
* because pg_time, pg_variable, and pg_log get created before their
* .bki file entries are processed.
*
> * As the result of this pretence it was possible to have in

when btree used in innerscan with run-time key which value
passed by pointer.
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.
