Commit200dd8e

committed

I'm sending you a small patch to pgdb.py module. This

raises pgdb.DatabaseError when any of the fetch*methods was invoked but previous call to execute* didnot produce any result set or no call was issued yet.Also, raises pgdb.NotSupportedError when .nextset() isinvoked, instead of NameError.This behaviour complies with DB-API 2.0.Thanks for your work!Timur Irmatov.
