Figured this out in https://github.com/simonw/simonwillisonblog/issues/132 - I was running PostgreSQL 9.x and I wanted 11.x in order to use the new
search_type="websearch" option in Django 3.1.
I followed the steps in Upgrading with pg:copy (I don't have any database followers so the
pg:upgrade route wasn't open to me).
Because I'm the only user who writes to my database I skipped the maintenance mode bit.
