It works, I did it for a while with the statement_timeout to change it globally over night when admin tasks were running. For the statement_timeout thing it wasn't optimal however, finally I had to ditch the thing... but it can be done. See below my shell script attached, it did work for me, YMMV. Cheers, Csaba. #!/bin/sh CONF_FILE=/var/lib/postgres/data-8_1_3p/postgresql.conf PG_CTL=/usr/local/postgres813p/bin/pg_ctl PG_DIR=/var/lib/postgres/data-8_1_3p TIMEOUT=0 if [ -n "$1" ]; then TIMEOUT=$1 fi cat $CONF_FILE | sed "s/^\(statement_timeout = \)[0123456789]\+/\1$TIMEOUT/" > $CONF_FILE.new mv $CONF_FILE.new $CONF_FILE $PG_CTL -D $PG_DIR reload
