pg_last_notice
(PHP 4 >= 4.0.6, PHP 5, PHP 7)
pg_last_notice — Returns the last notice message from PostgreSQL server
Descrierea
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.
