 Priority:  blocker                |  Milestone:  PostGIS 3.3.3
Component:  build/upgrade/install  |    Version:  3.3.x

 When installing a PostGIS version with extensions disabled you end up with
 a NEW shared library (.so) but no new .control file for extension.

 In this scenario, `postgis_extensions_upgrade()` will complan that you can
 NOT downgrade, thinking you're having the NEW version and attempting to
 bring you to the OLD version (from the .control file).

 It sounds like the "OLD" version should be read from script-only, not from
 .so file, so this sounds like a bug to be fixed ASAP.

 The guard against downgrade was introduced with
 [497e793493ccf96492665cbeab7482484e3f2a36/git] which was 3.3.0dev
