PostgreSQL DB Sync ​

DB Sync is a tool that takes care of two-way synchronisation between Mergin Maps and PostGIS databases. The synchronisation works both ways: changes made in a PostGIS database are automatically pushed to a configured Mergin Maps project and changes made in a GeoPackage in the Mergin Maps project are pushed to the PostGIS database.

Interested in using DB Sync? Go to MerginMaps/db-sync repository for the source code and a Quick start that will guide you through the steps to get DB Sync up and running.

Windows users may use a Windows executable for DB sync. On Linux/Mac users are advised to use a docker container. DB Sync configuration wizard can help you with creating the configuration file.
