These days the filter step of my script looks like grep -v -e 'grep postgres:' -e 'postgres: stats' -e 'postgres: writer' -e 'p ostgres: wal writer' -e 'postgres: checkpointer' -e 'postgres: archiver' -e 'pos tgres: logger' -e 'postgres: autovacuum' | \ In any case you could (and should) have just done "attach 13379" to get control of the process you wanted. The "ps | grep" dance is just an aid, not something that is guaranteed to work every time. regards, tom lane
