Geo - The Geo nodes admin page display secondary database state incorrectly

On the Geo nodes admin page, the status screen for a Geo secondary node shows:

However, running the query on Rails console looks fine. Notice pg_is_in_recovery has the right value:

[1] pry(main)> ActiveRecord::Base.connection.execute('SELECT pg_is_in_recovery()').first
   (0.4ms)  SELECT pg_is_in_recovery()
=> {"pg_is_in_recovery"=>true}

It looks like this is a regression due to the upgrade to Rails 5. We check if the query returns the string t, but now this query returns true or false.
