Description:
------------
There is a typo in function.pg-last-oid.php.

Example 1 is actually a pg_last_oid example but not pg_last_error() example.


Expected result:
----------------
Example 1. pg_last_oid() example
<?php
  $pgsql_conn = pg_connect("dbname=mark host=localhost");
 
  $res1 = pg_query("CREATE TABLE test (a INTEGER) WITH OIDS");

  $res2 = pg_query("INSERT INTO test VALUES (1)");
 
  $oid = pg_last_oid($res2);
?> 

Actual result:
--------------
Example 1. pg_last_error() example
<?php
  $pgsql_conn = pg_connect("dbname=mark host=localhost");
 
  $res1 = pg_query("CREATE TABLE test (a INTEGER) WITH OIDS");

  $res2 = pg_query("INSERT INTO test VALUES (1)");
 
  $oid = pg_last_oid($res2);
?>
