PostgreSQL 13 update from PostgreSQL 10 fails

Continuing the discussion from PostgreSQL 13 update:

I’m in a multisite with 2 container configuration (only postgres.10 and redis templates on the data container). The current version of postgres is 10 and I’d like to update to 13. Here is the error I get when I rebuild the data container:

Success. You can now start the database server using:

    /usr/lib/postgresql/13/bin/pg_ctl -D /shared/postgres_data_new -l logfile start

./discourse-doctor may help diagnose the problem.

If I set postgres.10 template again, everything works.
Do you know what I can do to upgrade to Postgres 13?

PS: Upgrade to postgres 12 is failing too

I saw that it’s require to stop de data container before:

Here is what I get I run tail -f shared/data/log/var-log/postgres/current after stopping the 2 containers:

It’s probably the source of the problem, how can I fix that?

out of curiosity, what is the owner of your postgres_data directory ?

Here it is

It is OK?

for my setup (2 containers, postgres 13) group for postgres_* is render not netdev, and postgres_run group right is x, not setgid. but I don’t really know what it implicates :sweat_smile:

ps. and redis_data is uuidd syslog …

Thanks, I don’t know neither :slight_smile:

Could you please run the same command with ls -lan? That will help with determining ownership (-n converts the username to UID and group name to GID). Here’s an example of my own site with 2 container setup:

[root@/var/discourse/shared/data]$ ls -lan
