When I look at a random Debian with the usual PGDG packages, the
postmaster process (and every backend) has a rather minimal environment
without HOME. When I remember the code correctly, walreceiver uses
the functions from fe-connect.c and may need to find the service file,
a password file or certificates. If I'm correct with that, requiring
HOME to be set would be a significant change for existing "normal"
installations.
What about containers and similar "reduced" environments?
Regards,
Christoph
