could u clarify this? shouldn't some kind of dictionary cache be employed?
this reminds me another issue I couldn't find explained in the docs - does
Postgres have some kind of library cache for sharing/reuse of SQL
statements, pl/pgsql functions, etc?
it seems that there is only buffer cache at present
thanx,
