Hi everyone, My name is Ken working in Tokyo,Japan. Please forgive my poor English. We have been using PostgreSQL7.3.4 on a Map GIS engine since last year.To tune the system, I need to get the log from PostgreSQL7.3.4 and analyze it. Here comes the problem. When a long SQL is excuted. I got the error as follow error:SQL Execute error 0 = Too much data was received. when I removed the log setting from my postgresql.conf file the sql was excuted without any problem and ended normally. I appand my postgresql.conf and start shell as follow. postgresql.conf ---------------------------------------------------------------- # # Message display # server_min_messages = log # Values, in order of decreasing detail: # debug5, debug4, debug3, debug2, debug1, # info, notice, warning, error, log, fatal, # panic client_min_messages = log # Values, in order of decreasing detail: # debug5, debug4, debug3, debug2, debug1, # log, info, notice, warning, error silent_mode = false log_connections = false log_pid = true log_statement = true log_duration = true log_timestamp = true # # Syslog # syslog = 1 # range 0-2 syslog_facility = 'LOCAL0' syslog_ident = 'postgres' LC_MESSAGES = 'C' LC_MONETARY = 'C' LC_NUMERIC = 'C' LC_TIME = 'C' ---------------------------------------------------------------- start_pgsql.sh ---------------------------------------------------------------- pg_ctl start -D /data/pgsql -o "-i" -l /data/pgsql/postgresql.log ---------------------------------------------------------------- develop environment OS: solaris2.9 Apserver: Sun application Server 7 JDBC Driver: pg74.215.jdbc3.jar can any friend help me, thanks a lot ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
