I've inherited a DB with a lot of legacy functions and aggregates that have an SFUNC of array_append and an STYPE of anyarray.
Upgrading to 14 fails as these need an STYPE of anycompatiblearray.
I'm only able to discover these by failing an upgrade and seeing the log. Is there some way I can query for these aggregates/functions and see how many I need to drop and have available to replace after a successful upgrade?
