That makes sense, really - I think you nailed it. We create a global
event, and for those that are "duplicates", it won't show up in the
second process.

I think the solution to this is to add the process id to the name of the
event. So instead of:
pgident: postgres: autovacuum launcher process
We'd ahve
pgident(12345): postgres: autovacuum launcher process

Seems reasomable? I'll be able to write up and properly test a patch
tomorrow.
