Update PostgreSQL to 11

Last time I run the tests from netbox with Postgres 12 I had some failures, that weren't there with 10 or 11. If they are gone now, I think the upgrade is OK. If not we should only go to version 11.

I did not do extended testing, so I trust in your judgment. 11 it is for now.

I think it's a good idea to go to 11.x so we always have the current minor version 👍

Hi!
we tried to upgrade from Netbox v2.6.7 to v2.6.11 (ldap) and also updated docker-compose to the latest version and the postgres 11 container exited with the following message:

docker logs -f 1a

is there a prefered way to upgrade the database?

Thank you!

Thank you for making me aware of this. Since I only use the Docker image for development, I can not provide a tried-and-tested answer to that question of yours.

There seem to be several proposals flowing around:

• Upgrading between major versions? docker-library/postgres#37 (comment)
• https://github.com/tianon/docker-postgres-upgrade

Note that there is no requirement to update to PostgreSQL 11, you can stick to version 10 just fine.
You could do this with a docker-compose.override.yml like so:

version: '3.4'
services:
  postgres:
    image: postgres:10-alpine

I have added a note to the preliminary changelog of the 0.20.0 release about this.
