columns. The returned tuple needs to have appropriate NULL columns inserted so that it actually matches the declared rowtype. It seemed convenient to use a JunkFilter for this, so I made some cleanups and simplifications in the JunkFilter code to allow it to support this additional functionality. (That in turn exposed a latent bug in nodeAppend.c, which is that it was returning a tuple slot whose descriptor didn't match its data.) Also, move check_sql_fn_retval out of pg_proc.c and into functions.c, where it seems to more naturally belong.
