Description:

> The already-mentioned ALTER SYSTEM command provides a SQL-accessible means
of changing global defaults; it is functionally equivalent to editing
postgresql.conf

Should not it be ...to editing postgresql.auto.conf?.. I know user is not
supposed to edit postgresql.auto.conf but this is what ALTER SYSTEM does,
not touching the postgres.conf - isn't is confusing in manual?..

Thank you
