Even if you "partition" the columns in the instrument
over N tables, you still can't query it in a single
result set.   The limit is quite deep in PostgreSQL
and extends to tuples, including views and in-memory
query results.

I find that partitioning does work, but it requires extra
care on the part of the application developer that really
shouldn't be necessary.

Best,

Clark
