We ran into a problem with a customer this weekend. They had >128,000

Would it make sense to have some sort of timeout for that?
I don't think you have diagnosed this correctly. Running out of lock
table slots generates an "out of shared memory" error, with a HINT that
you might want to increase max_locks_per_transaction. If you can prove
otherwise, please supply a test case.
You are correct, I didn't have all the information from my team members.
Not that it should surprise you that you are correct ;)
Thanks for replying.
