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.

If on "accident" your program passes pg_result_status a variable that is NOT a actual pg resource, it will return an empty string.
(This is important to know if you want to make sure a pg resource is "good" before attempting some operation on it).
