There was a problem hiding this comment.
I have two concerns at this point:
- User might lose unsaved changes. Should we not check if project is dirty and ask if he wants to save changes first?
- The dialog is visible and frozen while the project is loading, which can take a while for big projects. Would it make sense to handle the project loading in the caller code, while also overriding the cursor?

The loading is done in caller instead in the dialog also with cursor override.

Description
This allows storing older versions of QGIS projects in PostgreSQL. The process is mostly handled by a function and a trigger in the DB.
There are two places to handle the turning on versions of projects and loading previous versions.
Browser
On schema, user has option to enable the feature (with confirmation dialog). The action is disabled if the versioning is already active for the schema.
On project user either has option to allow versioning on the parent schema of the project
If the versioning is already active the user can see the versions of the project.
Open From.../Save To...
In those menus the user can also enable the feature and select previous version to load.
When loading QGIS project from schema that has versions activated the user can select older version of the project to load, by selecting it in the QTableWidget. If nothing is selected there the active version of QGIS project is loaded.
Fixes #62299
