Flush relcache entries when their FKs are meddled with Back in commit 100340e2dcd0, we made relcache entries keep lists of the foreign keys applying to the relation -- but we forgot to update CacheInvalidateHeapTuple to flush those entries when new FKs got created or existing ones updated/deleted. No bugs appear to have been reported that would be explained by this ommission, but I noticed the problem while working on an unrelated bugfix which clearly showed it. Fix by adding relcache flush on relevant foreign key changes.
Backpatch to 9.6, like the aforementioned commit.
