(Mapping Postgres a, Renderable a, Parsable a, OIDMapping a) => Mapping Postgres [a]

Maps to Postgres arrays.

Please note that since String is just an alias to [Char], it will be mapped to an array of characters. If you want to map to a textual type use Text instead.

Mapping Postgres a => Mapping Postgres (Maybe a)

Maps to the same type as the underlying value, encoding the Nothing as NULL.

(Mapping Postgres a, Renderable a, Parsable a, OIDMapping a) => Mapping Postgres (Vector a) 
data Connection Postgres = Connection {} 
data Result Postgres = Result {}
