I have a problem with postgres, I'm running a query that joins two tables, one with 129000+ records, and the other with 1172 records, it's a very simple join. But postgres can't handle it!!! (Both tables have an index on the field "cuentacb"). I get the following error after 3 minutes... migracion=# select * from cuentasequivalentes, equiv11mayo m migracion-# where cuentasequivalentes.cuentacb = m.cuentacb migracion-# and cuentasequivalentes.cuentabr <> m.cuentabr; FATAL 1: Memory exhausted in AllocSetAlloc() pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Succeeded. What can I do? I'm guessing that I could change a configuration parameter or something like that, but I don't know. Please help me, it's kind of urgent.
