"exec format error" when upgrading to Postgres 11 on ARM
I'm currently trying to update to postgres 11 since I want to update my monocontainer funkwhale to 0.21-rc1. I precise that the instance is running on an Pi (so with an arm architecture).
Steps to reproduce
Upgrade instructions from postgres 10 to 11 for docker all-in-one only in releases page.
Status: Downloaded newer image for tianon/postgres-upgrade:10-to-11
standard_init_linux.go:211: exec user process caused "exec format error"
What is expected?
I suppose a message saying that the upgrade is successful.
I presume that the problem is linked to the fact that it's an arm architecture, but I don't really know how to change the command to make it work, or if I have to upgrade the database another way. I'm not really used to the utilisation of postgres, so I'll continue to search if I've done something wrong and delete or update this issue if I find a solution.
