Maybe because there is no such function that would return an error code in PostgreSQL's C api, only one that returns an error message. At least the Sybase extension too seems to lack error codes, whether the reason is the same I don't know. So, I guess the DB extension and upcoming DB_* modules should somehow cope with the fact that there possibly aren't any error codes... :( Can't think a way of how. Parsing the error messages could/would be quite heavyweight, and anyway, they have a tendency to slightly change in different versions. Time to file a feature request to some of the PostgreSQL mailing lists. > But the API change in error codes of the pgsql extention may causes some > imcompatibility problem with the old codes which depend on the current > error codes. > I think the new function handling the error codes > should be added to maintain the compatibility. Well, maybe the day PostgreSQL gets error codes. -- Jouni Ahto
