It really seem powerful and useful, even in its free version. I will
evaluate it and eventually buy it.

Anyway it doesn't support SQLite. My app use SQLite to handle single
installation (no client/server) and offline work (sycronization with
the server beforehand) to simplify the installation of a more
lightweight client part.
Is there an easy way to convert a PostGreSQL database designed with
Toad in a SQLite database?
Actually, just the create commands are needed, the rest is optional.

Or in case, is there a better way to allow persistent data to be
stored and syncronized from and to a PostGreSQL server without
installing a PostGreSQL server on every client?
