The following bug has been logged online: Bug reference: 4513 Logged by: Alexey Bashtanov Email address: bashtanov@imap.cc PostgreSQL version: 8.3.1 Operating system: Red Hat Linux 2.6.20-1.2320.fc5smp i686 Description: VACUUM FULL fails with "out of memory" error Details: Hello! Such a thing happens: when I make an attempt to vacuum full a table it waits some minutes and then throws an error: ERROR: out of memory DETAIL: Failed on request of size 288. It doesn't matter I set maintenance_work_mem to 16MB, 200MB or 1GB. This table is bad enough: it has a size of 154G but "explain select *" says there are only 524597 rows (and that value seems to be near to true). It is not wide: integer, integer, character varying(10), integer, character varying(3), date, integer. Here's the part of serverlog: ========== TopMemoryContext: 49416 total in 6 blocks; 8776 free (46 chunks); 40640 used TopTransactionContext: 2986336304 total in 367 blocks; 192312 free (1088 chunks);
