pg_last_notice

Описание

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 from PHP 4.3.0.

Notice message logging can be set to optional by setting 0 for pgsql.log_notice in php.ini from PHP 4.3.0. Unless pgsql.ignore_notice is set to 0, notice message cannot be logged.
