By default, autovacuum isn't even turned on --- you have to enable it
and also stats_row_level if you want to use autovac. I don't have
enough experience with it to say whether the other settings are
adequate.

SIGINT (ie query cancel) is safe enough. If that doesn't work within a
few seconds, try SIGTERM (there is controversy over how safe that is,
but people do use it).
