This function is useful it may not return a full non fatal error but you want to see if the query completes anyway.
example
<?PHP
//connect to pg database
// create PGSQL
$PGSTAT = pg_result_status($PGSQL);//defaults to long
//And run it through a check for example
if(($PGSTAT == 1) || ($PGSTAT == 2)){
// for query results;
}else if(($PGSTAT == 3) || ($PGSTAT == 4)){
// for copy results;
}
if(($PGSTAT != 0) && ($PGSTAT != 5) && ($PGSTAT != 6) && ($PGSTAT != 7)){
// your code;
}else{
// $ERRORS codes;
}
// This is worked the best for me so far I tried using
// The command tag and I seem to still get an numeric result
//example
//$PGSTAT = pg_result_status($PGSQL, PGSQL_COMMAND_OK);
// got something like tuples ok so I recommend just use default long
?>
or use what ever condition check you feel fit

The postgres docs say that PHP should never be able to return PGRES_NONFATAL_ERROR
"A result of status PGRES_NONFATAL_ERROR will never be returned directly by PQexec or other query execution functions" http://www.postgresql.org/docs/current/static/libpq-exec.html
Therefore you cannot use this function to check if this query produced a notice.
