The issue isn't with reading them and interpreting them, it's what happens when you run ALTER SYSTEM and it goes and modifies the file. Presently, it basically operates on the first entry it finds when performing a SET or a RESET. Which also means that you can issue SET's to your heart's content, and if there's a duplicate for that GUC, you'll never actually change what is interpreted. Thanks, Stephen
