Hello all,
In order to speed up commonly used queries, I use prepared
statements. I assume that 'prepare' tells some database query planner to
take a look at a query, and do all preparations for it, then store those
preparations somewhere for when it's needed.
When I use CREATE FUNCTION to create a function, does that also get
"planned" automatically (plsql, specifically). My gut feeling is that it
doesn't (mainly since it can be any external language).
by the way, query plans are exposed through spi interface so all pl
languages have ability to store plans. pl/sql saves plans as well as
static sql in pl/pgsql. ymmv on various other pls.
