I stand corrected; there *is* something in the index itself which marks it
primary.

I'd guess that since the only time 'REFERENCES' is seen is when creating a
new table (and translated into hard-coded triggers after that), you should
be fine until you create a new table referencing the table whose primary
index you removed.

It's an inconsistency I would not feel comfortable with, so I'm glad I
learned about indisprimary.  Is this documented anywhere?
