I upgraded an internal DB to v14b1, but it took several tries, since there were
errors during pg_restore regarding aggregates using polymorphic functions
anyarray, which are now anycompatiblearray.
I succeeded in upgrading after dropping our aggregates.
I have a backup from the v13 DB, and it restores okay on v13.
However it fails with the same errors when restoring into v14.
I think this was all known, so I'm just adding a data point.
It's be easy enough to replace our "anyarrays" with "anycompatiblearrays".
But I think this should be called out as an incompatible change in the release
notes.
