check for "/var/lib/postgresql/9.4/data/base" failed: No such file or directory #29
Description
Hi there.
First of all many thanks to all the people involved in this project for their time.
I'm trying to follow the provided example in the README, and I get an error.
Steps to reproduce
mkdir -p postgres-upgrade-testing
cd postgres-upgrade-testing
OLD='9.4'
NEW='9.5'
docker pull "postgres:$OLD"
docker run -dit \
--name postgres-upgrade-testing \
-v "$PWD/$OLD/data":/var/lib/postgresql/data \
"postgres:$OLD"
sleep 5
docker logs --tail 100 postgres-upgrade-testing
docker exec -it \
-u postgres \
postgres-upgrade-testing \
pgbench -i -s 10
docker stop postgres-upgrade-testing
docker rm postgres-upgrade-testing
docker run --rm \
-v "$PWD":/var/lib/postgresql \
"tianon/postgres-upgrade:$OLD-to-$NEW" \
--link
Expected behaviour
See a success message in the standard out
Found behaviour
The process stopped with an error message:
The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.

Success. You can now start the database server using:
pg_ctl -D /var/lib/postgresql/9.5/data -l logfile start
WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Additional information
- Operating system: GNU/Linux debian Debian GNU/Linux bullseye/sid \n \l
- Docker version: 19.03.8, build afacb8b7f0
I'm almost sure that the root cause of the issue is the owner of the docker host directories.
The start of the workaround will require re-building a custom image with something like below:
ARG GNAME='groupname'
ARG GID=123
ARG USERID=113
# fix permissions so it can persist data on the host nfs file system
RUN groupadd -g $GID $GNAME \
&& usermod -g $GNAME postgres \
&& usermod -u $USERID postgres
