Re: pg_dumpall from a script

That looks great, but it doesn't really help with my problem unless I'm
missing something (very possible!)

I need a way to backup either from SQL in PSQL (possibly \!) or from a
PG/PLSQL function to a file with a name set from a :variable.

This would be triggered by a certain action in the database (applying a
patch).

Hope that's a bit clearer!

Cheers,
