And you can do the same thing with any of the PL languages that have database
drivers like Perl or Python. It might be a little less inefficient using one
of them -- and probably a lot less code.
You should be aware of the risk of deadlocks if you touch the same resources.
Because the database is unaware that your main transaction is waiting for this
other session to complete it won't be able to detect any deadlocks that depend
on this hidden dependency.
