Which version of PostGIS are you coming from again?
In theory, as long as your old is running a newish PostGIS 3+, it should be safe enough to just NOT run SELECT postgis_extensions_upgrade(); If you don’t run that, then your database is just running with a newer lib file, but old scripts. So then just installing the binaries of older should work fine. One caveat, I believe we did make sure changes that caused some functions not to work, but I can’t remember what those were. All I know is if you run SELECT postgis_full_version(); And you get an error after upgrading your binaries, then not running postgis_extensions_ugprade is not an option.

Apart from removing new packages and installing old ones and then restoring the database from backup , do we have any other option? Thanks, Nikhil
