Stan Hu b6125f7045 Fix fast admin counters not working when PostgreSQL has secondaries
This commit does a number of things:

1. Reduces the number of queries needed by perform a single query to get all
the tuples for the relevant rows.

2. Uses a transaction to query the tuple counts to ensure that the data
is retrieved from the primary.
