Are you open for a Postgresql client?

[mariochavez]

I have created a new Postgresql Gush::Client. It is API-compatible with the Redis client.

I have monkey-patched the client since Gush doesn't allow client replacement in our app.

We are still testing this patch, and so far, it looks good.

This addition will require changing Gush to allow Client swapping by configuration.

I have considered using SQL databases as storage instead of Redis. Would it work only for Postgres or would it be generic enough to support everything ActiveRecord does?

[mariochavez]

I don't use any Postgresql-specific features, MySQL, or SQLite3 support to store JSON documents, so it should work on ActiveRecord.

Let me extract and clean up my code, and I can start with a PR for code Review and Discussion.
