The following bug has been logged online: Bug reference: 2311 Logged by: Chris Hodgson Email address: [EMAIL PROTECTED] PostgreSQL version: 7.4.7 Operating system: Linux Fedora Core 3 Description: Toast table chunk_id overflow Details:
If you cycle through enough id's in your toast tables, the chunk_id goes past 2^32 and wraps around, leaving you in an intermittent error state. Inserting further toasted chunks will fail depending on whether that particular next id from the sequence is already in the table or not. It really shouldn't be possible to get into this state. There is obviously a hard limitation of using 4-byte integers as ids for the toasted chunks... I don't know what the solution is, but at very least an error message that is more clear about what has happened than repeated, seemingly random occurences of "duplicate key in table pg_toast.pg_toast_1834831156_index". ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
