Works here with PHP 5.2.3 and 5.2.2:

  $res = pg_query($conn, 'select assvg(the_geom) from floodplain6');
  while ($row = pg_fetch_assoc($res)) {
      echo 'isset   = ', isset($row['assvg']), "\n";
      echo 'empty   = ', empty($row['assvg']), "\n";
      echo 'is_null = ', is_null($row['assvg']), "\n";
      echo 'strlen  = ', strlen($row['assvg']), "\n";
  }
  pg_free_result($res);

I get the following output with both native PostgreSQL calls and
with PDO:

  isset   = 1
  empty   = 
  is_null = 
  strlen  = 114164

Can you provide a simple PHP script that demonstrates the problem
you're seeing?
