You really ought to vacuum and/or analyze occasionally. The EXPLAIN results show that the planner hasn't got any non-default statistics for any of these tables.
Wow, thanks for that. I'd been pulling my hair out for a couple of days wondering where I was going wrong.
I went from 45 second queries down to sub second query lengths after a simple vacuum full analyze.
I've now added nightly and monthly cron jobs to do this for me in future.
Out of curiosity, why is this deemed a DBA task rather than an automated postgres task?
Once again, many thanks.
