Migrated issue, originally created by Anonymous

The firebird backend translates Firebird's types incorrectly.

Firstly, a firebird LONG is 32 bits, a INT64 is 64 bigs. Secondly, all firebird integer types have a precision and scale. If they are 0 the raw type can be used, otherwise NUMERIC must be used.

The attached patch fixes the problem. The patch is for 0.7.8, but master looks the same.
