Me and a friend are testing some operations for a search application in PostgreSQL. In version 8.1 my friend tried to copy the result of a join into another table, about 45.000.000 (small) records. This is the result: testsearch=> insert into t_documentword2 (SELECT document_id, t_word2.id, frequency from t_documentword, t_word2 where t_documentword.word = t_word2.word); server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request. The connection to the server was lost. Attempting reset: Failed. He got the same result in version 7.5.15. Anyone any ideas what this could be?
