It looks like you're trying to run pl/pgsql code directly as SQL.
Postgres draws a distinction between those things, much more sharply
than Oracle does.  You need to create a function to run pl/pgsql
code in.  See the examples in the pl/pgsql part of the manual.

(If you're using PG 9.0, you only need a DO block, so the notational
overhead for a throwaway piece of code is a lot less ... but it's
still a distinct environment.)
