What version are you using? The test case you gave causes a repeatable core dump in 6.5 for me, so it was pretty easy to find the cause. I have committed a fix for 6.5.1, but if you are in a hurry: *** pl/plpgsql/src/pl_exec.c.orig Tue May 25 12:15:17 1999 --- pl/plpgsql/src/pl_exec.c Sat Jul 3 21:03:01 1999 *************** *** 2486,2491 **** --- 2486,2494 ---- * 2.
