Was wondering if something is worked to get a pool of cached query plan in
Postgresql ?
the topic [cached query plan] on the TODO list is a bit out of date and i
believe this feature could decently improve performance.

We haven't gone any farther than what you see in the TODO list detail.

Also it would be nice to se the use of "prepared statements" and "host
arrays" in the PG API, as these are the key to optimal use of "cached query
plans", and is supported in several SQL interfaces (JDBC).

Some guys on my university made an implementation of cached query
plans on Postgres as they degree thesis. I don't know the details,
but if there is interest I might be able to contact them (they might
be already reading this list, OTOH...)
