The following patch might just do the former. Please try it out.

return arays nicely without having to make the plperl programmer aware
of anything. The attached patch allows plperl to return an arrayref
where the function returns an array type. It silently calls a perl
function to stringify the array before passing it to the pg array
parser. Non-array returns are handled as before (i.e. passed through
this process) so it is backwards compatible. I will presently submit
regression tests and docs.
example:
andrew=# create or replace function blah() returns text[][] language
plperl as $$ return [['a"b','c,d'],['e\\f','g']]; $$;
CREATE FUNCTION
andrew=# select blah();
blah
-----------------------------
{{"a\"b","c,d"},{"e\\f",g}}
This would complete half of the TODO item:
. Pass arrays natively instead of as text between plperl and postgres
(The other half is translating pg array arguments to perl arrays - that
will have to wait for 8.1).
Some of this patch is adapted from a previously submitted patch from
Sergej Sergeev. Both he and Abhijit Menon-Sen have looked it over
briefly and tentatively said it looks ok.

for PL/Perl, to avoid loading the entire result set into memory as the
existing spi_exec_query() function does.
Here's how one might use the new functions:
$x = spi_query("select ...");
while (defined ($y = spi_fetchrow($x))) {
...
return_next(...);
}
The changes do not affect the spi_exec_query() interface in any way.

The Problem: Occassionally a DBA needs to dump a database to a new
encoding. In instances where the current encoding, (or lack of an
encoding, like SQL_ASCII) is poorly supported on the target database
server, it can be useful to dump into a particular encoding. But,
currently the only way to set the encoding of a pg_dump file is to
change client_encoding in postgresql.conf and restart postmaster.
This is more than a little awkward for production systems.

into pg_catalog rather than public, and supports dumping languages whose
handlers are found there. This will make it easier to drop the public
schema if desired.
Unlike the previous patch, the comments have been updated and I have
reformatted some code to meet Alvarro's request to stick to 80 cols. (I
actually aghree with this - it makes printing the code much nicer).
I think I did the right thing w.r.t versions earlier than 7.3, but I
have no real way of checking, so that should be checked by someone with
more/older knowledge than me ;-)

when a plpython function returns unicode" thread:
http://archives.postgresql.org/pgsql-bugs/2005-06/msg00105.php
In several places PL/Python was calling PyObject_Str() and then
PyString_AsString() without checking if the former had returned
NULL to indicate an error. PyString_AsString() doesn't expect a
NULL argument, so passing one causes a segmentation fault. This
patch adds checks for NULL and raises errors via PLy_elog(), which
prints details of the underlying Python exception. The patch also
adds regression tests for these checks. All tests pass on my
Solaris 9 box running HEAD and Python 2.4.1.
In one place the patch doesn't call PLy_elog() because that could
cause infinite recursion; see the comment I added. I'm not sure
how to test that particular case or whether it's even possible to
get an error there: the value that the code should check is the
Python exception type, so I wonder if a NULL value "shouldn't
happen." This patch converts NULL to "Unknown Exception" but I
wonder if an Assert() would be appropriate.
The patch is against HEAD but the same changes should be applied
to earlier versions because they have the same problem. The patch
might not apply cleanly against earlier versions -- will the committer
take care of little differences or should I submit different versions
of the patch?

The specification of this function is as follows.
regexp_replace(source text, pattern text, replacement text, [flags
text])
returns text
Replace string that matches to regular expression in source text to
replacement text.
- pattern is regular expression pattern.
- replacement is replace string that can use '\1'-'\9', and '\&'.
'\1'-'\9': back reference to the n'th subexpression.
'\&' : entire matched string.
- flags can use the following values:
g: global (replace all)
i: ignore case
When the flags is not specified, case sensitive, replace the first
instance only.

inspection of shared catalogs. This allows pg_dumpall to continue to
work with pre-8.1 servers that likely won't have a database named postgres.
Also, suppress output of SYSID options for users and groups, since server
no longer does anything with these except emit a rude message.
There is much more to be done to update pg_dumpall for the roles feature,
but this at least makes it usable again. Per gripe from Chris K-L.

plperl - the attached small patch remedies that omission, and adds a
small regression test for error and warning output - the new regression

find myself typing a command and then wanting to get the syntax for it.
So I do a ctrl-a and add a \h: but psql does not recognize the command,
because I have stuff attached to it (e.g. "alter table foobar"), so I
have to scroll over and delete everything except the name of the command
itself. This patch gives \h three chances to match: if nothing matches
the complete string (current behavior), it tries to match the first two
words (e.g. "ALTER TABLE"). If that fails, it tries to match the first
word (e.g. "DELETE").

This patch allows the PL/Python module to do (SRF) functions.
The patch was taken from the CVS version.
I have modified the plpython.c file and have added a test sql script for
testing the functionality. It was actually the script that was in the
8.0.3 version but have since been removed.
In order to signal the end of a set, the called python function must
simply return plpy.EndOfSet and the set would be returned.
