[postgis-users] [postgis-devel] Error Upgrading PostGIS 2.5.4 to 3.1.2

[Nikhil Shetty]

Hi Sandro,

Thank you, I will try the workaround

BUT I'm wondering: why would you want to upgrade to 3.1.2 when the
latest PostGIS version in the 3.1 branch is 3.1.8 ?
 -- We started with the upgrade at a time when 3.1.2 was the latest
version. We will try to add the newer version in future upgrades.

Thanks,
Nikhil
