My 2 cents: Use pg_dumpall -g to dump only the global objects Use pg_dump -Fc to dump the individual databases in the cluster. This gives you a compressed dump file. Furthermore it allows you to restore some subset of the database fairly easily should the need arise (see another recent thread where the OP wanted to restore only two tables out of a pg_dumpall file). > > My last question is does anyone know how I can easily automate my > backups for PostgreSQL in Linux using Cron or some well written script > someone has on the web?
