Обсуждение: pgsql: Process options from the startup packed in walsender.

Log Message:
-----------
Process options from the startup packed in walsender. Only few options
make sense for walsender, but for example application_name and client_encoding
do. We still don't apply per-role settings from pg_db_role_setting, because
that would require connecting to a database to read the table.
