I meant that pg_cancel_backend() should still work on autovac workers,
contrary to Alvaro's suggestion that autovac workers should sometimes
ignore SIGINT.
Basically the implementation vision I have is that the SIGINT catcher in
an autovac worker should remain stupid, and any intelligence involved
should be on the side where we're deciding whether to send a signal or
not. This probably does involve exposing more state in PGPROC but I see
nothing much wrong with that. (It might be time to merge inVacuum,
isAutovacuum, and the additional state into a bitwise vacuumFlags field.)
