Checking whether I can upgrade my postgres 17 database to postgres 18, I get this error:
upgrade installed extensions before attempting a major version upgrade
Looking at the extensions I have installed, I have:
- plpgsql 1.0
- postgis 3.5.0
Any suggestions on ways forward here? The error itself is somewhat cryptic, so I don’t even know if the issue is the versions of these extensions that are installed.
