If we don't have multi-table indexes how do we enforce a primary key

The executor would have to be clever enough to not do a single index
scan, but possibly scan through multiple indexes when asking for
uniqueness, depending on the partitioning rule set.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
