Thanks for your answer.I would like to avoid compiling as much as possible.I know that postgis 3.2.1 is available and does install without pb. but..That db run an app which is very long to test, so I need to stick to a postgis 3.0.x
I’m not particularly fluent here but working from the PostGIS project homepage and into the linked package archives I do not see where what you want exists. It doesn’t seem like the 3.0.x series is being kept up-to-date in packaged form.
But you may want to use PostGIS support channels to have a better chance at getting confirmation/help rather than here.
My general impression is that the packaging, at least for Debian, doesn’t actually understand how the PostGIS project handles versioning support. But i may be missing something as I’m doing this web-only and apt.postgresql.org is basically impossible to inspect on the web.
