Trouble with restore: "invalid command \restrict"

Bug
1

I’m having trouble doing a restore from “Discourse 3.5.0.beta9-dev - 04dbc622ab1e0197d16703ba47cf005ec93697ee” to current (6f06709643fa5e2253606c46f79d089ca3393ac9)

invalid command \restrict
EXCEPTION: psql failed: invalid command \restrict

If I remove these printf commands from database_restorer, it works:

      <<~CMD
        (
          printf '%s\\n' "\\\\restrict #{nonce}"
          #{sed_command}
          printf '%s\\n' "\\\\unrestrict #{nonce}"
        ) | #{self.class.psql_command} 2>&1
      CMD

It looks like this commit.

On the version where the backup was made (a cdck docker container) I have this :

PostgreSQL 15.13 (Debian 15.13-1.pgdg120+1) on x86_64-pc-linux-gnu, compiled by gcc (Debian 12.2.0-14) 12.2.0, 64-bit

and this is where I’m trying to restore (dev site running pg15 on the bare metal):

PostgreSQL 15.13 (Ubuntu 15.13-1.pgdg22.04+1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 11.4.0-1ubuntu1~22.04) 11.4.0, 64-bit

I don’t understand what this code is trying to do, so I’m just confused.

You need to be on PG 15.14 and you need to make sure all your instances are on that. This patches a large security issue.

Aha. That’s a very simple explanation.

Thanks. I’ll get on that.
