Agreed, I wanted the ability to hold a session at hand a couple of times already for tests. And I agree with the point of having a separate discussion for such things out of the scope of a bug fix. Thinking larger, I think that it would be more helpful to hold processes and run commands in parallel, say for pg_receivewal. > Can't do that with isolationtester ... In the pglogical fork of Postgres, you guys improved isolationtester to handle multiple hosts, right? That sounds harder to integrate than a perl module though, as isolation tester starts only one server. -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
