I am just know comming to grips with the various transaction_isolation level that can be chosen.
I notice that postgresql.conf file comes with 'read committed' pre-set.
I am wondering why is 'read commited' chosen over any of the other isolation levels such as
SERIALIZABLE?
A more generalized question would be, are there any application/RDBMS design considerations to
help determine the best default isolation level?
