Thread: pgsql: Modify pg_stat_get_activity to build a tuplestore

Modify pg_stat_get_activity to build a tuplestore

This updates pg_stat_get_activity() to build a tuplestore for its
results instead of using the old-style multiple-call method.  This
simplifies the function, though that wasn't the primary motivation for
the change, which is that we may turn it into a helper function which
can filter the results (or not) much more easily.
