Thank you for the reply, but I'm not sure what you mean.
To give more context (which I should have not straight off)
I'm on an old box which is running PoshgreSQL 8.3 for both the server and
client (psql).
The select from table, create function, and select from function are all
happening in the same psql sesson, logged in the owner of the database.
