postgresql_server: enable auto_explain and set to 30s

Browse source 
This will log an explain for any query that takes more than 30s.
We likely will need to lower it to get the slow heavy queries that are
hitting koji's db.

This does require a restart, but after this we can change the min
duration with just a reload. If there are too many logs, we can set this
to -1 to never log.
