Postlite
Postgres wire compatible SQLite proxy
...The proxy translates PostgreSQL frontend messages into SQLite transactions, then converts SQLite results back into PostgreSQL-compatible responses. It also mirrors parts of the PostgreSQL catalog through an attached in-memory database with virtual tables. This helps GUI clients inspect schema and system information more successfully. Postlite is useful as a reference for protocol translation, SQLite administration experiments, and lightweight database tooling, but it is no longer maintained.
