Hi,
Is there any way to do this?
For context, I'm wanting to write a custom script in repeatable read isolation
level. If I hit a serializable error, I don't want the client to abort, I want
it to continue running transactions. Is that possible?
Catch the exception/error and retry:
http://www.postgresql.org/docs/9.4/interactive/transaction-iso.html#XACT-REPEATABLE-READ
"When an application receives this error message, it should abort the
current transaction and retry the whole transaction from the beginning.
The second time through, the transaction will see the
previously-committed change as part of its initial view of the database,
so there is no logical conflict in using the new version of the row as
the starting point for the new transaction's update.
thanks,
Brad.
