Further information. What did you do, what did you expect?

Similar to #607, some of the generated tests are erroring out with pq: encode: unknown type for types.NullDecimal. Followed instructions on https://github.com/volatiletech/sqlboiler/#diagnosing-problems to pin ericlargergren/decimal version to v0.0.0-20181231230500-73749d4874d5 which worked up till SQLBoiler v4.13.0. But seems like SQLBoiler v4.14.0 pins that library to a newer version v0.0.0-20211103172832-aca2edc11f73 which brings back the error.
