Description

   mixed pg_update ( resource connection, string table_name, array data,
   array condition [, int options])

   pg_update() updates records that matches condition with data. If
   options is specified, pg_convert() is applied to data with specified
   options.

   <?php
       $db = pg_connect('dbname=foo');
       $data = array('field1'=>'AA', 'field2'=>'BB');

       // This is safe, since $_POST is converted automatically
       $res = pg_update($db, 'post_log', $_POST, $data);
       if ($res) {
           echo "Data is updated: $res\n";
       } else {

       }
