Problem with postgres upgrade

I"m trying to help someone who refused to upgrade to PG13 and now has an expired SSL cert.

It may be made more difficult because of Apt-get update fails inside container yarn repo not signed - #5 by pfaffman, but I modified the pg12 and pg13 templates so that they should work, but I can’t get it to upgrade and I can’t get it to rebuild with the pg12 template.

Here’s what happens when I tried to do the upgrade:

fixing permissions on existing directory /var/lib/postgresql/12/main ... ok          
creating subdirectories ... ok
selecting dynamic shared memory implementation ... posix
selecting default max_connections ... 100

Success. You can now start the database server using:
    pg_ctlcluster 12 main start

Consult the last few lines of "pg_upgrade_dump_16566.log" for
the probable cause of the failure.

You can run ./launcher start app to restart your app in the meanwhile

Trying to rebuild without the upgrade has stuff like the below when it tries to migrate the database:

PG::InsufficientPrivilege: ERROR:  permission denied to create extension "unaccent"                                                                    

I think I’ll have to revert to a clean install and the latest backup, which is several days old.

Can’t you add the below to hooks to create the unaccent extension if it’s missing?

    - exec: su postgres -c 'psql discourse -c "create extension if not exists unaccent;"'

Sounds like a plan! I’ll check it out on the morning. Thanks

Looks like that did it! I had to add it to the pg12 and postgres.

Well, it did it enough to get it running again with PG12, but I never got the PG13 upgrade to work. I made a backup. moved the postgres stuff to a backup directory, rebuilt, and restored the backup.
