[GENERAL] Corruption in postgres 7.4 on solaris 2.9.
I am running postgres 7.4 and solaris 2.9 and I fear I have a corruption. The database runs fine for a while and then a command will receive the following: psql: FATAL: xlog flush request 8/20D70938 is not satisfied -- flushed only to 6/FDBA6540 CONTEXT:writing block 180816 of relation 17143/17477 This occurs many times with the "flushed only to" value never changing. Eventually the server must be restarted. I tried using the pgfsck tool and get the following: -- Detected database format 7.4 -- Loading pg_class structure -- Scanning table pg_class (1259) -- Table pg_class(1259):Page 0: Incorrect value in header (incorrect blocksize?) -- 00 00 00 00 00 66 A6 70 00 00 00 0B 00 E4 01 50 20 00 20 01 -- Table pg_class(1259):Page 0: Incorrect value in header (incorrect blocksize?) -- 00 00 00 00 00 66 D9 F0 00 00 00 0B 00 E4 01 90 20 00 20 01 -- Table pg_class(1259):Page 0: Incorrect value in header (incorrect blocksize?) -- 00 00 00 00 00 67 6D F0 00 00 00 0B 00 E0 01 90 20 00 20 01 -- Table pg_class(1259):Page 0: Incorrect value in header (incorrect blocksize?) -- 00 00 00 00 00 67 B4 A0 00 00 00 0B 00 D4 02 B0 20 00 20 01 Couldn't find class 'pg_attribute' I believe the block size is 8192 and I have tried others to no avail. Is there a way to determine the corrupt area and remove it? I have read pg_filedump can help but I have not been able to find a Solaris version.

Straight 7.4. No dot release. I do not doubt this could be a problem within the version I am using. However, I am looking for a way to correct/recover the database.
