Cygwin with the possible exception of mSQL-interface. Since I don't
have mSQL installed, I skipped this tool.
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.
The procedure to apply the patch is as follows:
$ # save the attachment as /tmp/contrib.patch
$ # change directory to the top of the PostgreSQL source tree
$ patch -p0 </tmp/contrib.patch

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
have unique indexes on them. Put back pg_rewrite_oid_index, which I
mistakenly removed a few days ago, and add pg_trigger_oid_index.
pg_stats to provide controlled (and, hopefully, more readable) access
to statistics. Comments on definition of pg_stats welcome.
I didn't force initdb, but the rules regress test will fail until you
do one.
Tom Lane). For the moment, only the OID/name variants are provided.
I didn't force initdb, but the additions to the 'privileges' regress
test won't pass until you do one.
database, including system catalogs (but not the shared catalogs,
since they don't really belong to his database). This is per recent
mailing list discussion. Clean up some other code that also checks
for database ownerness by introducing a test function is_dbadmin().
inet(text), cidr(text): convert a text value into inet/cidr
set_masklen(inet): set masklen on the inet value
Patch also contains regression checks for these functions.

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
USERSET context.
manipulation of rtable/jointree by planner. Rewriter was generating
actions that shared rtable/jointree substructure, which caused havoc
when planner got to the later actions that it'd already mucked up.
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.
Rationalize locking of pg_shadow, pg_group, pg_attrdef (no need to use
AccessExclusiveLock where ExclusiveLock or even RowExclusiveLock will do).
Also, hold locks until transaction commit where necessary.
when built against readline 4.2. Specifically, it handles the deprecation
of
filename_completion_function()
with preference for
rl_filename_completion_function()
Although, I was motivated by Cygwin support, IMO this patch is appropriate
for all platforms. To quote from the readline source:
#if 0
/* Backwards compatibility (compat.c). These will go away sometime. */
...
extern READLINE_EXPORT(char, *filename_completion_function) ...
#endif
Note that this patch is modeled after the one by Peter Eisentraut for
completion_matches():
http://www.ca.postgresql.org/~petere/readline42.html
I tested this patch under the following environments:
Cygwin with readline 4.1
Cygwin with readline 4.2
Linux with readline 2.2.1
Linux with readline 4.2
and it behaved as expected.

submit. These were done for the jdbc2 driver. The first one is for support
of the Types.BIT in the PreparedStatement class. The following lines need to be
inserted in the switch statment, at around line 530:
(Prepared statment, line 554, before the default: switch
case Types.BIT:
if (x instanceof Boolean) {
set(parameterIndex, ((Boolean)x).booleanValue() ? "TRUE" : "FALSE");
} else {
throw new PSQLException("postgresql.prep.type");
}
break;
The second one is dealing with blobs,
inserted in PreparedStatemant.java (After previous patch line, 558):
case Types.BINARY:
case Types.VARBINARY:
setObject(parameterIndex,x);
break;
and in ResultSet.java (Around line 857):
case Types.BINARY:
case Types.VARBINARY:
return getBytes(columnIndex);
