-- No new functions were added in 2.0, but we need to recreate the existing
-- functions.
-- We expect pxf.control's MODULE_PATHNAME to point to a new location
-- outside of $GPHOME and inside $PXF_HOME.
-- We will require users to perform an `ALTER EXTENSION pxf UPDATE`
-- to reflect the new module_pathname in pg_proc.
-- To check the updated pg_proc run the following query:
-- select prosrc, probin from pg_proc where proname like '%pxf%';
