This makes me wonder if we should not just add a shortcut in
recordMultipleDependencies() to use recordDependencyOn if there is
only one reference in the set.  That would save the effort of a multi
insert for all callers of recordMultipleDependencies() this way,
including the future ones.  And that could also be done independently
of the addition of InsertPgAttributeTuples(), no?
