Note that you can also take advantage of plan caching by using prepared
statements (PREPARE, EXECUTE and DEALLOCATE). These are also session
local, however (i.e. you can't share prepared statements between
connections).

You can't share plans among different sessions at the moment. Can you
elaborate on why you can't use persistent or pooled database
connections?
