Re: Pg_dumpall

I have cron execute a Python script as the database
administrator to vacuum and backup all databases.
Rather than dump all databases at once, however, the
script performs a 'pgsql -l' to get a current list of
databases. Each database is dumped and piped into
gzip for compression into its own backup file.

I should also mention that the script renames all
previous backup files, all ending in *.gz, to
*.gz.old; so that they survive the current pg_dump.
Of course, you could change the script to put the date
in the file name as to keep unlimited backup versions.

If you'd like the script, let me know.

Best of Luck,
