I have POSTGIS="2.4.3 r16312" on my linux server and I need to upgrade it to POSTGIS="2.4.4 r16526" or any newer version. I use the following:
ALTER EXTENSION postgis UPDATE;
but it gives me the apparante message:
version "2.4.3" of extension "postgis" is already installed
Would you plesae let me know if how to upgrade the PostGIS version?
