Hi, I use psql (PostgreSQL) 8.1.10 on my box, there is a postmater process running automatically to make temp files in pgsql_tmp folder, I don't do any query on my database. Anybody knows what's wrong with it? and how to find what the postmater process is for Thanks Dong He -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
