 Our changes:
  * adodb-lib.inc.php - forced conversion to proper numeric type in _adodb_column_sql()
+ * drivers-adodb-postgres7.inc.php - removed (commented) one buggy ServerInfo() call that
+       was preventing PG version detection to work. http://tracker.moodle.org/browse/MDL-6647
+       Once solved by adodb guys, we'll undo this (affects to version v4.92a of ADOdb)
