Hpgsql.TypeInfo

Description

This file has is very similar to a similarly named file from the great postgresql-simple library, more specifically to https://hackage.haskell.org/package/postgresql-simple-0.7.0.0/docs/src/Database.PostgreSQL.Simple.TypeInfo.Static.html We started with that and later came up with our own from scratch, though. We thank them for their great work.
