pqstream

Postgres-backed Event Library for Go

TODO

Improve docs (about considerations, setup example, if pqstream works across sessions etc)
Better logging, possibly with an optional Zerolog adapter
Authorization hooks for subscription which provide access to the http req, res, and the topic requested in order to allow or block access to a topic list
Better configurability? Different encoders (Msgpack, Protobuf etc)
