Re: Postgres provider to use gda-srv lib

["Peter C. Norton" <spacey lenin nu>]

I've started to re-write the db2 server to use the gda-mysql-server from
cvs, too.  

I agree on point 1, for case 2 can you provide a scenario where an unknown
type can come back out of the database, and why a varchar2 would be the
right datatype?  Are you thinking of a user-defined object? Dunno about 3
yet.
