| The text format used is the same as used by PostgreSQL, so you can also use the **''.dump''** command to export an SQLite database into a PostgreSQL database.

| You can almost (but not quite) go the other way and export a PostgreSQL database into SQLite using the **pg_dump** utility. Unfortunately, when **pg_dump** writes the database schema information, it uses some SQL syntax that SQLite does not understand. So you cannot pipe the output of **pg_dump** directly into **''sqlite''**. But if you can recreate the schema separately, you can use **pg_dump** with the **-a** option to list just the data of a PostgreSQL database and import that directly into SQLite. | You can almost (but not quite) go the other way and export a %%PostgreSQL%% database into SQLite using the **pg_dump** utility.
