Error when upgrading Postgres version

[2mol]

I've swapped out the underlying database for version 12.1 on Heroku. I'm now getting errors similar to #57, and I'm unable to reset the metadata.

When resetting the metadata in the console, I get "unexpected : relation "hdb_catalog.hdb_function" does not exist".

I know I could have followed a proper migration as described in the docs, but there wasn't any data yet, so I just intend to set the Postgres version to 12.1 and then load data into it from a dump.

Is the intention that you can't do a hard-reset of Hasura's metdata on a fresh DB without going through the procedure of backing up the metadata?
