SQLedge uses Postgres logical replication to stream the changes in a source Postgres database to a SQLite database that can run on the edge. SQLedge serves reads from its local SQLite database, and forwards writes to the upstream Postgres server that it's replicating from.

This lets you run your apps on the edge, and have local, fast, and eventually consistent access to your data.

Should be much faster for reads than hitting the full PSQL DB, but lacks features like aggregation and triggers. Wonder if this could be incorporated into Lemmy for any benefit.
