[postgis-devel] Upgrade PostGIS from 2.5.4 to 3.1.2

[Nikhil Shetty]

Hi Regina,

Thank you for sharing the steps.Yes, we are upgrading the database as well
from 11.7 to 13.4.

I saw the steps you shared and I will give it a try.

Does uninstalling postgis25_11 have any impact on a running Postgres
database that is using postgis25_11 functions?? Wanted to know which step
will cause a downtime to the application apart from the database upgrade
step.

Thanks and Regards,
Nikhil
