Why? pg_ctl -o is defined as an option to which is given a
string. This string includes a set of options to pass down to the
"initdb" or "postgres" commands kicked by pg_ctl when interacting with
a. In this case, "-p 5432 -b " looks like a valid option value to
me. This means to start a server with port 5432, disabling
autovacuum, something that pg_upgrade requires.
