For various workloads, compression could be a win on both disk space and speed (see, e.g., http://blog.oskarsson.nu/2009/03/hadoop-feat-lzo-save-disk-space-and.html). I realize Postgresql doesn't have general table compression a la InnoDB's row_format=compressed (there's TOAST for large values and there's some old discussion on http://wiki.postgresql.org/wiki/CompressedTables), but I thought I'd ask: anybody tried to compress their PG data somehow? E.g., any positive experiences running PG on a compressed filesystem (and any caveats)? Anecdotal stories of the effects of app-level large-field compression in analytical workloads (though I'd be curious about transactional workloads as well)?
