Yea, I started a thread about it:
https://www.postgresql.org/message-id/20190306204104.yle5jfbnqkcwykni%40alap3.anarazel.de

In short, I think this was basically not this patch's fault, it just
added an assertion that coincidentally triggered for the changes in
https://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=807ae415c54628ade937cb209f0fc9913e6b0cf5
et al. When pg_upgrading from pre v12, we're creating a partitioned
table that doesn't have a relfilenode, but does have a toast table.
