Your premise is wrong --- pg_ctl does not read postgresql.conf at any
time. It's not intended to be used in a scenario where the
data_directory configuration option is being used.
There have been previous discussions about trying to teach it to read
the config file, but the effort needed seems far out of proportion to
the benefits :-(
