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. Closes #46742	2018-05-25 22:58:43 -07:00
Stan Hu	e38938b332	Fix Error 500 viewing admin page due to statement timeouts ... Uses PostgreSQL tuple estimates to provide a much faster yet approximate count. See https://wiki.postgresql.org/wiki/Slow_Counting for more details. We only use this fast method if the table has been analyzed or vacuumed within the last hour.
