Postlite

Postlite is a network proxy to allow access to remote SQLite databases over the Postgres wire protocol. This allows GUI tools to be used on remote SQLite databases which can make administration easier.

The proxy works by translating Postgres frontend wire messages into SQLite transactions and converting results back into Postgres response wire messages. Many Postgres clients also inspect the pg_catalog to determine system information so Postlite mirrors this catalog by using an attached in-memory database with virtual tables. The proxy also performs minor rewriting on these system queries to convert them to usable SQLite syntax.

Note: This software was a proof of concept of wrapping SQLite with the Postgres wire protocol. It is no longer maintained. You're welcome to fork this project if you're interested in continuing development.

Usage

To use Postlite, execute the command with the directory that contains your SQLite databases:

$ postlite -data-dir /data

On another machine, you can connect via the regular Postgres port of 5432:

$ psql --host HOSTNAME my.db

This will connect you to a SQLite database at the path /data/my.db.

Development

Postlite uses virtual tables to simulate the pg_catalog so you will need to enable the vtable tag when building:

$ go install -tags vtable ./cmd/postlite
