Andres Freund 4c9e1bd0a3 Reset memory context once per tuple in validateForeignKeyConstraint. 
When using tableam ExecFetchSlotHeapTuple() might return a separately
allocated tuple. We could use the shouldFree argument to explicitly
free it, but it seems more robust to to protect

Also add a CHECK_FOR_INTERRUPTS() after each tuple. It's likely that
each AM has (heap does) a CFI somewhere in the relevant path, but it
seems more robust to have one in validateForeignKeyConstraint()
itself.

Note that this only affects the cases that couldn't be optimized to be
verified with a query.
