a new postmaster child process. This should eliminate problems with
authentication blocking (e.g., ident, SSL init) and also reduce problems
with the accept queue filling up under heavy load.
The option to send elog output to a different file per backend (postgres -o)
has been disabled for now because the initialization would have to happen
in a different order and it's not clear we want to keep this anyway.

SI messages now include the relevant database OID, so that operations
in one database do not cause useless cache flushes in backends attached
to other databases. Declare SI messages properly using a union, to
eliminate the former assumption that Oid is the same size as int or Index.
Rewrite the nearly-unreadable code in inval.c, and document it better.
Arrange for catcache flushes at end of command/transaction to happen before
relcache flushes do --- this avoids loading a new tuple into the catcache
while setting up new relcache entry, only to have it be flushed again
immediately.

modifiable repositories, I have a clean untrusted plperl patch to offer
you :)
Highlights:
* There's one perl interpreter used for both trusted and untrusted
procedures. I do think its unnecessary to keep two perl
interpreters around. If someone can break out from trusted "Safe" perl
mode, well, they can do what they want already. If someone disagrees, I
can change this.
* Opcode is not statically loaded anymore. Instead, we load Dynaloader,
which then can grab Opcode (and anything else you can 'use') on its own.
* Checked to work on FreeBSD 4.3 + perl 5.5.3 , OpenBSD 2.8 + perl5.6.1,
RedHat 6.2 + perl 5.5.3
* Uses ExtUtils::Embed to find what options are necessary to link with
perl shared libraries
* createlang is also updated, it can create untrusted perl using 'plperlu'
* Example script (assuming you have Mail::Sendmail installed):
create function foo() returns text as '
use Mail::Sendmail;
%mail = ( To => q(you@yourname.com),
From => q(me@here.com),
Message => "This is a very short message"
);
sendmail(%mail) or die $Mail::Sendmail::error;
return "OK. Log says:\n", $Mail::Sendmail::log;
' language 'plperlu';

Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.
I tested the build aspect of this patch under Cygwin and Linux without
any ill affects. Note that I did not actually attempt to test the code
for functionality.

CatalogCacheFlushRelation (formerly called SystemCacheRelationFlushed)
how to distinguish tuples it should flush from those it needn't; this
means a relcache flush event now only removes the catcache entries
it ought to, rather than zapping the caches completely as it used to.
Testing with the regression tests indicates that this considerably
improves the lifespan of catcache entries. Also, rearrange catcache
data structures so that the limit on number of cached tuples applies
globally across all the catcaches, rather than being per-catcache.
It was a little silly to have the same size limit on both, say,
pg_attribute caches and pg_am caches (there being only four possible
rows in the latter...). Doing LRU removal across all the caches
instead of locally in each one should reduce cache reload traffic
in the more heavily used caches and improve the efficiency of
cache memory use.
TopTransactionContext, rather than using Dllist. This simplifies and
speeds up the code, and eliminates a former risk of coredump when
out of memory (since the old code didn't bother to check for malloc
failure). It also moves us one step closer to retiring Dllist...
detected sooner in backend startup, and is treated as an expected error
(it gives 'Sorry, too many clients already' now). This allows us not
to have to enforce the MaxBackends limit exactly in the postmaster.
Also, remove ProcRemove() and fold its functionality into ProcKill().
There's no good reason for a backend not to be responsible for removing
its PROC entry, and there are lots of good reasons for the postmaster
not to be touching shared-memory data structures.
rules and triggers by OID. So, even though we have no cross-references
in the system catalogs to pg_rewrite.oid or pg_trigger.oid, we'd better

datatypes, not only strings. parse_hook is useless for bool, I suppose,
but it seems possibly useful for int and double to apply variable-specific
constraints that are more complex than simple range limits. assign_hook
is definitely useful for all datatypes --- we need it right now for bool
to support date cache reset when changing Australian timezone rule setting.
Also, clean up some residual problems with the reset all/show all patch,
including memory leaks and mistaken reset of PostPortNumber. It seems
best that RESET ALL not touch variables that don't have SUSET or

It "make"s and "make check"s clean against current cvs tip.
There are now both Text and Name variants, and the regression test support
is rolled into the patch. Note that to be complete wrt Name based variants,
there are now 12 user visible versions of has_table_privilege:
has_table_privilege(Text usename, Text relname, Text priv_type)
has_table_privilege(Text usename, Name relname, Text priv_type)
has_table_privilege(Name usename, Text relname, Text priv_type)
has_table_privilege(Name usename, Name relname, Text priv_type)
has_table_privilege(Text relname, Text priv_type) /* assumes current_user */
has_table_privilege(Name relname, Text priv_type) /* assumes current_user */
has_table_privilege(Text usename, Oid reloid, Text priv_type)
has_table_privilege(Name usename, Oid reloid, Text priv_type)
has_table_privilege(Oid reloid, Text priv_type) /* assumes current_user */
has_table_privilege(Oid usesysid, Text relname, Text priv_type)
has_table_privilege(Oid usesysid, Name relname, Text priv_type)
has_table_privilege(Oid usesysid, Oid reloid, Text priv_type)
For the Text based inputs, a new internal function, get_Name is used
(shamelessly copied from get_seq_name in sequence.c) to downcase if not
quoted, or remove quotes if quoted, and truncate. I also added a few test
cases for the downcasing, quote removal, and Name based variants to the
regression test.

tclodbc (http://sourceforge.net/projects/tclodbc) and libiodbc-2.50.3
(http://www.iodbc.org/dist/libiodbc-2.50.3.tar.gz). I could not
get either to work... postgres would not find the global odbcinst.ini
file. I traced this to src/interfaces/odbc/gpps.c -- here are the
many things I think are wrong:
Run tclodbc and do a ``database db <DSNname>'' where ``DSNname'' is
one of the DSN's in /usr/local/etc/odbcinst.ini (or wherever the
global ini file is installed.) The result is always the error
message that ``one of server,port,database,etc. are missing''.
Run libiodbc-2.50.3/samples/odbctest <DSNname>. The command fails
to connect to the database and just exits.

pg_database now has unique indexes on oid and on datname.
pg_shadow now has unique indexes on usename and on usesysid.
pg_am now has unique index on oid.
pg_opclass now has unique index on oid.
pg_amproc now has unique index on amid+amopclaid+amprocnum.
Remove pg_rewrite's unnecessary index on oid, delete unused RULEOID syscache.
Remove index on pg_listener and associated syscache for performance reasons
(caching rows that are certain to change before you need 'em again is
rather pointless).
Change pg_attrdef's nonunique index on adrelid into a unique index on
adrelid+adnum.
Fix various incorrect settings of pg_class.relisshared, make that the
primary reference point for whether a relation is shared or not.
IsSharedSystemRelationName() is now only consulted to initialize relisshared
during initial creation of tables and indexes. In theory we might now
support shared user relations, though it's not clear how one would get
entries for them into pg_class &etc of multiple databases.
Fix recently reported bug that pg_attribute rows created for an index all have
the same OID. (Proof that non-unique OID doesn't matter unless it's
actually used to do lookups ;-))
There's no need to treat pg_trigger, pg_attrdef, pg_relcheck as bootstrap
relations. Convert them into plain system catalogs without hardwired
entries in pg_class and friends.
Unify global.bki and template1.bki into a single init script postgres.bki,
since the alleged distinction between them was misleading and pointless.
Not to mention that it didn't work for setting up indexes on shared
system relations.

yield the same ordering as a btree index scan. To be really sure that
that equivalence holds, we use the btree entries in pg_amop to decide
whether we are looking at a '<' or '>' operator. For a sort operator
that has no btree association, we put the nulls at the front if the
operator is named '>' ... pretty grotty, but it does the right thing in

value of DESTDIR like the rest (or at least most) of the PostgreSQL
makefiles. I found this problem when trying to package a pre-built
Cygwin PostgreSQL distribution, but this problem is platform independent.
The problem manifests itself when one tries to install into a stagging
area (e.g., to build a tarball) instead of a real install. In this case,
pg.py and _pgmodule$(SO) still end up being installed in the configured
prefix directory ignoring the value of DESTDIR.
Unfortunately, this patch does not handle the case where PostgreSQL
and Python are configured with different prefixes. Since the Python
Makefile is automatically generated and does not use DESTDIR, I believe
that this issue will be difficult to correct. If anyone has ideas on
how to fix this issue, then I'm quite willing to rework the patch to
take the suggestion into account.

under Cygwin. The root cause of this problem is that (Sun) java is a

The solution is to use Cygwin's cygpath utility to convert the Posix style

- New functions to create a portal using a prepared/saved
SPI plan or lookup an existing portal by name.
- Functions to fetch/move from/in portals. Results are placed
in the usual SPI_processed and SPI_tuptable, so the entire
set of utility functions can be used to gain attribute access.
- Prepared/saved SPI plans now use their own memory context
and SPI_freeplan(plan) can remove them.
- Tuple result sets (SPI_tuptable) now uses it's own memory
context and can be free'd by SPI_freetuptable(tuptab).
Enhancement of PL/pgSQL
- Uses generic named portals internally in FOR ... SELECT

- Support for CURSOR and REFCURSOR syntax using the new SPI

Here's what I came up with. The biggest difference api between JDK1.x and
later versions is the support for collections. The problem was with the
Vector class; in jdk1.x there is no method called add, so I changed the
calls to addElement. Also no addAll, so I rewrote the method slightly to not
require addAll. While reviewing this I notices some System.out.println
statements that weren't commented out. So I commented them out in both
versions.
The upshot of all of this is that I have clean compile, but no idea if the
code works ;(

PageGetFreeSpace() was being called while not holding the buffer lock, which
not only could yield a garbage answer, but even if it's the right answer there
might be less space available after we reacquire the buffer lock.
Also repair potential deadlock introduced by my recent performance improvement
in RelationGetBufferForTuple(): it was possible for two heap_updates to try to
lock two buffers in opposite orders. The fix creates a global rule that
buffers of a single heap relation should be locked in decreasing block number
order. Currently, this only applies to heap_update; VACUUM can get away with
ignoring the rule since it holds exclusive lock on the whole relation anyway.
However, if we try to implement a VACUUM that can run in parallel with other
transactions, VACUUM will also have to obey the lock order rule.
