Re: pg_dumpall from a script

[James Sewell <james.sewell@xxxxxxxxxxxx>]

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,

Hello,

I need to trigger a database dump from a SQL script (or function, but I think that is even less likely).

I know I can do:

\! pg_dumpall > /mydir/myfile

Which is fine, but I need to use a variable to set the name.

\set myfile 'filename'

\! pg_dumpall > /mydir/:myfile

Doesn't seem to work.

Any ideas?
