pglogical

This is a technical server-side module that changes how Odoo sends database structure changes (DDL) to PostgreSQL. When configured, it intercepts those changes and forwards them to the replica sets you choose, so copies of the database receive the same table and column updates as the main database.

• It only activates if a pglogical section exists in the Odoo configuration file and lists one or more replication sets. Without that, it does nothing.
• It requires the Python library sqlparse; if that library is missing, the feature is disabled and an error is logged.
• It does not run during automated tests.
• It automatically adds the public schema name to table and column names in the intercepted statements when needed, while leaving temporary tables and certain statements (like those involving aggregates, constraints, triggers, or indexes) untouched.
• It does not add any menus, screens, buttons, reports, or user-facing settings in Odoo. There are no new models or business rules for end users.

In short, it is an infrastructure tool for administrators who use pglogical replication and want schema changes to propagate automatically.
