# PostgreSQL DB Sync
Integrating with other databases is an important feature provided by the DB sync tool, hosted in lutraconsulting/mergin-db-sync (opens new window) repository. It takes care of synchronisation of changes between a Mergin project and a PostgreSQL database. The synchronisation works both ways: it pushes changes from PostgreSQL to Mergin and it also pulls changes from Mergin to PostgreSQL. Please see the project page for more details.
