I am also attaching a new version of the patches where we scope the
new constraint recreating behavior to UNIQUE and PK constraints
(instead of everything that is index-backed). This avoids unwanted
impact on how FKs that reference partitioned tables are handled and
should as a bonus fix the CI.

Thanks,
Álvaro
