pg_last_notice() returns the last notice message from the PostgreSQL server on the specified connection
. The PostgreSQL server sends notice messages in several cases, for instance when creating a SERIAL column in a table.
With pg_last_notice(), you can avoid issuing useless queries by checking whether or not the notice is related to your transaction.
Notice message tracking can be set to optional by setting 1 for pgsql.ignore_notice in php.ini.
Notice message logging can be set to optional by setting 0 for pgsql.log_notice in php.ini. Unless pgsql.ignore_notice is set to 0, notice message cannot be logged.

<?php $pgsql_conn = pg_connect("dbname=mark host=localhost"); $res = pg_query("CREATE TABLE test (id SERIAL)"); $notice = pg_last_notice($pgsql_conn); echo $notice; ?>
The above example will output:
