<para>
<function>pg_last_notice</function> returns the last notice
message from the PostgreSQL server on the specified
<parameter>connection</parameter>. The PostgreSQL server sends notice
messages in several cases, for instance when creating a <literal>SERIAL</literal>
column in a table.
</para>
<para>
With <function>pg_last_notice</function>, you can avoid issuing useless
queries by checking whether or not the notice is related to your transaction.
</para>
<warning>
<para>
This function is EXPERIMENTAL and it is not fully implemented
yet. <function>pg_last_notice</function> was added in PHP
4.0.6. However, PHP 4.0.6 has problem with notice message
handling. Use of the PostgreSQL module with PHP 4.0.6 is not
recommended even if you are not using
<function>pg_last_notice</function>.
</para>
<para>
This function is fully implemented in PHP 4.3.0. PHP earlier than
PHP 4.3.0 ignores database connection parameter.
</para>
</warning>
<para>
Notice message tracking can be set to optional by setting 1 for
<literal>pgsql.ignore_notice</literal> in &php.ini; from PHP 4.3.0.
</para>
<para>
Notice message logging can be set to optional by setting 0 for
<literal>pgsql.log_notice</literal> in &php.ini; from PHP 4.3.0.
Unless <literal>pgsql.ignore_notice</literal> is set
to 0, notice message cannot be logged.
