See: http://www.postgresql.org/docs/8.2/interactive/sql-createtable.html So, the answer is no. Also note that currently Postgres will cache information about tables used in functions and this may not work well when you are dropping and recreating tables with the same name in the same session. For that kind of thing you need to use EXECUTE to avoid caching.
