Don't worry about that. Before anything user could do, postgres's
start up procedure sets the appropreate encoding to ClientEncoding
variable.
Also please note that "wanted is after connection set as default
ClientEncoding same encoding as actual DabaseEncoding" is not
corrent. The ClientEncoding might be set differently if
PGCLIENTENCODING is set before postmaster starts up.
