Comment (by David Sanders):
Just FYI to folks subscribed to this ticket:
In addition to having composite FKs for multitenancy, there's also the new
temporal PK/FK feature in Postgres 18 (currently beta) that will be useful
for declaring temporal tables: https://www.depesz.com/2024/10/03/waiting-
for-postgresql-18-add-temporal-foreign-key-contraints/
tl;dr it adds the new `PERIOD` qualifier to FKs for declaring timestamp
range constraints, which will likely be used in a composite key alongside
the record identifier.
Multitenancy I already use frequently and I anticipate I'll make quite
good use of temporal keys :)
