Hi, I've got troubles today with my db, my postmaster freeses at every 10-15 minutes. I looked to the logs, and I've found the next error: ERROR: cannot open segment 1 of relation pg_proc_oid_index and sometimes it is followed by: ERROR: SearchSysCache: recursive use of cache 9 It seems to me, that there's some corruption in the pg_proc_oid_index relation, but I don't know how to correct it, becouse it's a system index, and I'm not allowed to drop it, and recreate it - I think this would be the most easy... Now I'm in troubles, becouse id something want to access this index relation, all my processes freeze in the startup phrase, I have to kill the postmaster and start it again. If someone experienced such things, plz elp me +--------------------------------------------+ | Nagy Attila | | mailto:[EMAIL PROTECTED] | +--------------------------------------------+ ************
