Upgrading from PostGIS 2.4.9 to master (3.3.0dev) on PG12 results in error

[robe]

It seems on dronie, we managed to get a PostGIS with 2.4.9 installed in PG12.

Now that we made PG12 live, it is trying to upgrade from PG 12 2.4.9 to 3.3.0dev

and failing on topology. This looks like issue with changes made in PG12 they took out. I think we had fixed the views for geography_columns and geometry_columns. So I suspect a similar change can be made on topology.
