FWIW, I see excessive memory consumption for this query in 8.2.x but
not in 8.3.x and later. Some desultory investigation suggests that
the change is associated with rangetable representation improvements
that were made in 8.3. Since 8.2.x is staring hard at its EOL date,
I suggest now might be a good time to update to a more recent release
series.
