RE: Refactor ECPGconnect and allow IPv6 connection

Yeah, I agree your argument that duplicated parse function should be removed.

ECPG parses connection string because it uses PQconnectdbParams()
even if target is specified in the new-style,
hence my elementary idea is that the paring can be skipped if PQconnectdb() calls.

I will try to remake patches based on the idea.
