Initial commit of PostgresKit, our new Postgres framework as a start towards adding PostgreSQL support to Sequel Pro.
Note, that the framerwork is by no means feature complete and in it's current state has quite a few limitations: - No support for Postgres' asynchronous query API - Only supports the very basic data types (char/text and numerics) - No support (outide of libpq) for re-establishing dropped connections Current feature support includes: - Basic connection handling - Query execution - Prepared statement execution - Encoding support similar to SPMySQL's
