Creating the temporary table first, and then inserting into it seems to
be a *somehow* functional workaround. However, the function cannot be
called again a second time during the same session, since the temporary
table already exists. Is there a way a table can be created  truly
temporary, existing only within the scope of a plpgsql function?
