a while back I posted a patch for pg_ident, the patch worked but I didn't
diagnose the problem properly.
on my compiler(gcc2.7.2) this compiles with no errors...
char buf[1000]; if(buf != '\0') {
...but it doesn't compare '\0' with the first char of buf.
There is an error in the configure script when using
--with-pgport= that will cause the compiled version of
PostgreSQL to no longer allow connections to the
new port and to treat shared memory improperly.
What happens is that if the port is changed, the configure
script defines DEF_PGPORT as "", which atoi() will return
as 0, which makes the IPC_KEY value 0. This then causes
semaphores to be allocated, but never released. Postgres
eventually returns from semget() with
"no space left on device". The source of this error could
easily be overlooked in version 6.3 since it is possible
to connect via UNIX domain sockets, and having DEF_PGPORT
defined as "0" would not be noticed until TCP was used.
The following patch is to src/interfaces/libpq of postgresql-6.3.
The purpose of the patch is to make the initialization of
const char *pgresStatus[] match the ExecStatusType enum.
6.3 postmaster is supposed to work with pre 6.3 protocol. This is true
for little endian architecture servers. But for big endian machines
such as Sparc the backward compatibility function do not work.
Attached are patches to fix the problem.
For substr() and substring() on the text data type, the relevant code is in
varlena.c. You are right, there is a problem. I have a patch which I will
apply to the source tree soon. The copy enclosed below probably does not
preserve tabs correctly so cannot be applied directly; the relevant change
is simply changing the ">=" to ">"...
It is my hope that the following "patches" to libpgtcl get included
in the next release.
See the update to the README file to get a full description of the changes.
This version of libpgtcl is completely interpreter-safe, implements the
database connection handle as a channel (no events yet, but will make it
a lot easier to do fileevents on it in the future), and supports the SQL
"copy table to stdout" and "copy table from stdin" commands, with the
I/O being from and to the connection handle. The connection and result
handles are formatted in a way to make access to the tables more efficient.
Included are patches intended for allowing PostgreSQL to handle
multi-byte charachter sets such as EUC(Extende Unix Code), Unicode and
Mule internal code. With the MB patch you can use multi-byte character
sets in regexp and LIKE. The encoding system chosen is determined at
the compile time.
To enable the MB extension, you need to define a variable "MB" in
Makefile.global or in Makefile.custom. For further information please
take a look at README.mb under doc directory.
(Note that unlike "jp patch" I do not use modified GNU regexp any
more. I changed Henry Spencer's regexp coming with PostgreSQL.)

Ok, this fixes three things:
1. It seems (from tests submitted by two people with JBuilder) that
JBuilder expects a responce from ResultSetMetaData.getPrecision() &
getScale() when used on non numeric types. This patch makes these
methods return 0, instead of throwing an exception.
2. Fixes a small bug where getting the postgresql type name returns null.
3. Fixes a problem with ResultSet.getObject() where getting it's string
value returns null if you case the object as (PGobject), but returns
the value if you case it as it's self.
Patch1:
Postgres thinks dist_pl (dist of a point to a line) is expecting a box (603)
for the right arg, but it really should be a line (628).
Otherwise the left & right args match those of dist_pb (dist of a point to a
box) two lines further down.
Patch2:
Anyways, these two functions take a path (602) whereas in pg_proc.h they are
listed as taking a lseg (601).
1. Make 'all' works without complaint. Don't have to add the .exp
files to the files list. They are made automagically when
making the respective shared lib file.
Only port that actually uses EXPSUFF (from makefiles/Makefile.*)
is Aix, so if this breaks anybody else, let me know, asap.
2. Make 'clean' actually cleans up correctly. Previously, it would
leave the .o files in C-code directory.
3. Changed references to reflect new location of .c files.
4. Added DELETE statements to complex.source so that it tidies up
when done. Previously, it would leave things in pg_amop,
pg_amproc and pg_opclass. Only possible to do this with the
new SUBSELECT code in 6.3. Nice work, fellas...
Not deleting the index entries would cause a non-fatal error if
complex.sql was run again on the same database. Much tidier now.
5. Corrected the README. obj directory hasn't existed since Bryan
redid the make way back when. Also changed the snipet from psql
to match the current version. POSTGRES95?!? I don't think so. :)
The following patches will allow postgreSQL 6.3 to compile and run on a
UNIXWARE 2.1.2 system with the native C compiler with the following library
change:
The alloca function must be copied from the libucb.a archive and added
to the libgen.a archive.
Also, the GNU flex program is needed to successfully build postgreSQL.
Seem to remember someone posting to one of the lists a while back
that the tutorial code wouldn't compile and/or run. Found four
problems with it that will let it run.
1. Tutorial makefile had a recursive use of DLOBJS.
2. Some tutorial needed semi-colons added to many statements.
3. Complex tutorial didn't clean up after itself.
4. Advanced had a time-travel example. Commented it out and
put a line pointing the user to contrib/spi/README.
Two incorrect printf formats in parser/parse_type.c. Prolly done
by me a long time ago when I cleaned up int's and Oid's...
Format flag is really just %u, not %ud. Harmless, but results in
"type id lookup of 25d failed" instead of only "...25 failed"
This patch will...
1. Remove the "-Wall" option from the ecpg/lib and ecpg/preproc Makefile.
2. Remove the addition of $(SRCDIR)/include and-or $(SRCDIR)/backend from
ecpg/lib, ecpg/preproc, libpq and utils Makefiles. Already in CFLAGS...
3. Set MK_NO_LORDER and RANLIB in Makefile.aix to avoid a couple of extra
steps taken care of by the 'ld' command anyways.
I thought it would be a good idea to ensure that the new view
permission model will not get broken by subsequent
fixes/changes. So I wrote a little regression test for it.
There is an ugly thing in this regression test. It creates
temporary a test user that is required for the tests. The
user is removed at the end of the test, but if sometimes the
regression suite is aborted or crashes exactly here, the test
user will lay around in the pg_shadow. Don't have a clue how
to get around.
return, not a slot returned from access method (they have
different TupleDesc and MergeJoin node was broken).
nodeIndexscan.c: index_markpos()/index_restrpos() call index-specific
mark/restr funcs and are in use now (instead of
IndexScanMarkPosition()/ExecIndexRestrPos()).
seems that my last post didn't make it through. That's good
since the diff itself didn't covered the renaming of
pg_user.h to pg_shadow.h and it's new content.
Here it's again. The complete regression test passwd with
only some float diffs. createuser and destroyuser work.
pg_shadow cannot be read by ordinary user.

What it does:
It solves stupid problem with cyrillic charsets IP-based on-fly recoding.
take a look at /data/charset.conf for details.
You can use any tables for any charset.
Tables are from Russian Apache project.
Tables in this patch contains also Ukrainian characters.
Then run ./configure --enable-recode
Ok. I have decided to use:
#if defined(sun) && if defined(sparc) && !defined(__svr4)
instead of defined(sunos4). interfaces/libpq/libpq-fe.h and
include/c.h have been modified(see included patches).
Another porblems I have found are:
o SunOS lacks strtoul(). to fix this I stole strtoul.c from FreeBSD
and place it under backend/port. necessary modifications have been
also made to backend/port/Makefile.in, include/config.h.in and
configure.in (see included patches).
So if the relname is given to acldefault() in
utils/adt/acl.c, it can do a IsSystemRelationName() on it and
return ACL_RD instead of ACL_WORLD_DEFAULT.
The diff looks so simple and easy. But to find it wasn't fun.
It must have been there for a long time. What happened:
When a tuple in one of some central catalogs was updated, the
referenced relation got flushed, so it would be reopened on
the next access (to reflect new triggers, rules and table
structure changes into the relation cache).
Some data (the tupleDescriptor e.g.) is used in the system
cache too. So when a relation is subject to the system cache,
this must know too that a cached system relation got flushed
because the tupleDesc data gets freed during the flush!
For the GRANT/REVOKE on pg_class it was slightly different.
There is some local data in inval.c that gets initialized on
the first invalidation of a tuple in some central catalogs.
This needs a SysCache lookup in pg_class. But when the first
of all commands is a GRANT on pg_class, exactly the needed
tuple is the one actually invalidated. So I added little code
snippets that the initialization of the local variables in
inval.c will already happen during InitPostgres().
