Ha ha, in another post, I just explained that the idea for the follow up
question came from EXPLAIN ANALYZE. Yes, the idea being to see if there was a
way to ask PG what tables/fields were used to output a specific result, field by
field, and then squelch these fields in our DB abstraction layer rather than in
the DB directly.
We're being asked to satisfy some pretty strict guarantees of data privacy
that were unanticipated when designing our product. Adding strict permissions
now would be an expensive proposition.
