First of all, you need to locate the problem SQL by modifying log
parameters.
sed -ir "s/#*logging_collector.*/logging_collector= on/"
$PGDATA/postgresql.conf
sed -ir "s/#*log_directory.*/log_directory = 'pg_log'/"
$PGDATA/postgresql.conf
sed -ir "s/#*log_statement.*/log_statement= 'all'/" $PGDATA/postgresql.conf
Execute this SQL and send error message in the log.
