Synapse Database Schemas

These schemas are used as a basis to create brand new Synapse databases, on both SQLite3 and Postgres.

Building full schema dumps

If you want to recreate these schemas, they need to be made from a database that has had all background updates run.

To do so, use scripts-dev/make_full_schema.sh. This will produce new full.sql.postgres and full.sql.sqlite files.

Ensure postgres is installed and your user has the ability to run bash commands such as createdb, then call

./scripts-dev/make_full_schema.sh -p postgres_username -o output_dir/

There are currently two folders with full-schema snapshots. 16 is a snapshot from 2015, for historical reference. The other contains the most recent full schema snapshot.
