Avoid using atooid for numerical comparisons which arent Oids
The check for the number of roles in the target cluster for an upgrade
selects the existing roles and performs a COUNT(*) over the result. A
value of one is the expected query result value indicating that only
the install user is present in the new cluster. The result was converted
with the function for converting a string containing an Oid into a numeric,
which avoids potential overflow but makes the code less readable since
it's not actually an Oid at all.
