Of course what I meant was if postgres stores execution plans for queries i=
n user-defined SQL functions. From the docs I can see that PL/PgSQL uses th=
e SPI-interface to create and store execution plans for queries for each co=
nnection. But I'll use the PREPARE function like Thomasz Myrta suggested.

Unless you know something I don't, I do not believe that PL/pgSQL stores=20
execution plans for functions.
