hi,
where can i find the postgis extension for postgressql-server 14 on sles12sp5?
@UweS Hi and welcome to the Forum 
I see https://postgis.net/documentation/getting_started/install_opensuse/ leading to https://build.opensuse.org/package/show/Application:Geo/postgis but no build for SLE 12 SP5, you might need to try rebuilding the src rpm locally (totally unsupported of course).
this is not the anwser i hope 
thanks for replay.
