Yeah, I'd been wondering about that too: we could strip the "Lock" suffix
from all the names in the LWLock category, and make pg_stat_activity
output a bit narrower.
There are a lot of other things that seem inconsistent, but I'm not sure
how much patience people would have for judgment-call renamings. An
example is that "ProcSignalBarrier" is under IO, but why? Shouldn't it
be reclassified as IPC? Other than that, *almost* all the IO events
are named SomethingRead, SomethingWrite, or SomethingSync, which
makes sense to me ... should we insist they all follow that pattern?
Anyway, I was just throwing this idea out to see if there would be
howls of "you can't rename anything" anguish. Since there haven't
been so far, I'll spend a bit more time and try to create a concrete
list of possible changes.
