NO NO don’t do that. Those set of libraries aren’t compatible with each other.
The PostGIS 3.0 and 2.5 from 12 are compatible with each other however. So What you want to do is cp /usr/lib/postgresql/12/lib/postgis-3.so /usr/lib/postgresql/12/lib/postgis-2.5.so cp /usr/lib/postgresql/12/lib/postgis_raster-3.so /usr/lib/postgresql/12/lib/rtpostgis-2.5.so cp /usr/lib/postgresql/12/lib/postgis_topology-3.so /usr/lib/postgresql/12/lib/postgis_topology-2.5.so Then after the upgrade in each of your databases run: SELECT PostGIS_Extensions_Upgrade(); And then run it again to rebundle the raster into it’s own extension SELECT PostGIS_Extensions_Upgrade(); Then if you don’t need raster, you can DROP EXTENSION postgis_raster; Once you are done upgrading your databases, you can delete thr *-2.5.so files you created in the 12 cluster.

I’m assuming apt.postgresql.org If so you should report on their mailing list, as that would be a packaging bug,not a PostGIS one and no one on the PostGIS project is on the apt team. https://www.postgresql.org/list/pgsql-pkg-debian/ Thanks, Regina From: postgis-users [mailto:postgis-users-boun...@lists.osgeo.org] On Behalf Of Stefan Wolf Sent: Friday, October 4, 2019 6:19 AM To: postgis-users@lists.osgeo.org <mailto:postgis-users@lists.osgeo.org> Subject: [postgis-users] PostgreSQL 12 and PostGIS Today I’ve installed the brand new PostgreSQL 12 on Ubuntu 18.04 “apt-get install postgis” will install PostGIS 2.5.2, but the PATH is wrong: /usr/share/postgresql/11/… So CREATE EXTENSION postgis will fail.
