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.

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_jobs" table.

There is certainly PL/TclU in the core distro.
