Uh, then what? The only idea I had was to set a static boolean variable in syscache.c that controls whether droppped columns are returned, and have a enable/disable functions that can turn it on/off. The only problem is that an elog inside a syscache lookup would leave that value set. My only other idea is to make a syscache that is like ATTNAME except that it doesn't return a dropped column. I could probably code that up if you wish. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000+ If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania19026
