[Mono-list] SqlMetal to PostgreSQL

I had brought this issue up a while back along with the "money" type.
And although the issue was marked as fixed, it seems as though there
was a major refactoring and now I cannot find the source file that
included these type mappings.

My question to the developers: is there no way to integrate this type
mapping stuff with the NpgsqlTypes.* classes?  I see that the
NpgsqlTypes.NpgsqlTypesHelper is an internal class, but can't the
source code be cannibalized somehow? I'm now license expert, but it
seems permissible enough:
