This is a good point. On the one hand, I do agree that the API for simple things like processing CSV files shouldn't be overly complex. So perhaps we could start with a simple API and extend it later. On the other hand, understanding how some of the more complex cases ought to work provides insight into handling the simpler cases. So I think we should aim to have at least a sketch of a design for the whole feature, and then if in phase 1 we want to implement only the easier parts, that's OK. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
