I saw this on the GENERAL list and this answer got me thinking.
Do JDBC Prepared statements get the same saved execution plan support?
We currently use PreparedStatements in our framework for JDBC access. We
currently do not retain the PreparedStatement between uses, but if
PostreSQL caches the execution plan, we may need to change our design.
Thanks,
Charlie
