A temp table will be dropped at the end of the connection. You can reuse it by adding ON COMMIT DELETE ROWS and then check
if it exists in your function with this other function: http://www.milwaukeesoft.com/forums/viewtopic.php?t=79 You can also use ON COMMIT in a couple of different ways: ON COMMIT The behavior of temporary tables at the end of a transaction block can be controlled using ON COMMIT. The three options are: PRESERVE ROWS No special action is taken at the ends of transactions. This is the default behavior. DELETE ROWS All rows in the temporary table will be deleted at the end of each transaction block. Essentially, an automatic TRUNCATE <http://www.postgresql.org/docs/8.1/interactive/sql-truncate.html> is done at each commit. DROP The temporary table will be dropped at the end of the current transaction block.
