<span class="function"><strong>pg_last_notice()</strong></span> returns the last notice
message from the PostgreSQL server on the specified

messages in several cases, for instance when creating a <em>SERIAL</em>
column in a table.

With <span class="function"><strong>pg_last_notice()</strong></span>, 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

Notice message logging can be set to optional by setting 0 for
