Please don't top-post, first, and second, it certainly seems like a
worthwhile thing to want to know, for a variety of reasons, such as
"what takes precedence- ALTER SYSTEM, or a configuration in
postgresql.conf?"

The regular postgresql.conf file is read first, then
postgresql.auto.conf and then pg_hba.conf and pg_ident.conf.  We can't
read pg_hba.conf/pg_ident.conf before reading postgresql.conf and
postgresql.auto.conf because their location is specified in
postgresql.conf/postgresql.auto.conf.

If you have log_connections enabled, we'll log the 'connection received'
message very shortly after fork'ing.

You could also enable DEBUG2 (or higher) to see the fork from the parent
process.

Thanks!
