JSONCDC
=======

JSONCDC provides change data control for Postgres, translating the Postgres
write ahead log to JSON.

It is written in Rust and, being short, is a good skeleton project for other
would be plugin authors who'd like to use Rust instead of C when writing
Postgres extensions.

Our library Requires rust stable 1.1 or greater.  You can bug `posix4e` (or
`posix4e_`) on Freenode if you want to get involved.

Tasks to work on should be available on:
