No, you need to call a function written in an untrusted language, such as
PL/perlu.

I think there's a pl/sh procedural language (in contrib or gborg iirc), but
you could probably use any of the untrusted procedural languages.
Better, would be to use the LISTEN/NOTIFY feature to talk to an external
daemon that handles things for you, otherwise your script will run as the
same user as the backend.

or plperl, or plphp too :)
I think the new version must run in safe mode, as it installs as a trusted
language, or at least that's the impression I got.

Please make sure you reply to the list too.
In your daemon you do something like: "LISTEN signal1", and in a trigger (say)
you issue "NOTIFY signal1". Your daemon will receive an asynchronoums message
"signal1" and you can then check the relevant tables for
updates/deletions/whatever signal1 means.
In practice, I usually don't care about responding that quickly, and just have
a cron job start up a script every 5 mins to check a "pending_jo bs" table.

There is certainly PL/TclU in the core distro.

I wonder if anyone can shed some light on a very frustrating problem.
I'm running a debian linux 3.0 "woody" server, nothing special, with

postgres version. Anywho - I'm trying to backup my databases, which I
did at one point, but I have no idea what happened, could have been an
upgrade. My Dbs...

We are trying to make some things work with plpgsql. The problem is that I

calling it was just making the assign:

which gave me an error near ")".
Now if I did the same, but like this:

Hmmm, I've always used plpgsql.so (also formerly known
as libplpgsql.so, I think...) as in:

LANGUAGE c;

Hi,
Thought perhaps some other eyes than mine can tell if I'm doing
something wrong here or if there's a bug somewhere. I've never
passed a ROWTYPE varaible to a function but I don't see where
the problem is.
I keep getting errors like (the first is my debug output):

I am trying to install OPenacs with postgres 7.4.3 as

FYI, mostly. But I do have questions as to how to write code
that will continue to work in subsequent postgresql versions.
See code below.
begintest() uses EXIT to exit a BEGIN block from within nested
loops. No problem.
begintest2() simplifies this, omitting the nested loops.
Still no problem.
