RE: pl/pgsql and returning rows

As a workaround, you can insert your row into an existing table, then
retrieve it from there later.  I think you need to enumerate all of the
fields, as in 'INSERT INTO table VALUES (ret.field1,
ret.field2,...ret.fieldn);'.  At least, I haven't succeeded any other way.
Messy, but the best method available right now.
