For example, there are several tests under contrib/ that create roles.  These would not be covered by this

It's been a while but if memory serves me right, one of the reasons for this
approach was that pg_regress didn't use libpq so running queries and storing
results for comparisons other than diffing .out files was painful at best.

Since 66d6086cbc pg_regress does have a dependency on libpq so we can now
perform that bookkeeping a bit easier.  I still find it more elegant to at
least compare the contents and not just the count, but I can take a stab at a
revised patch since this approach doesn't seem to appeal to the thread.
