Note that commit 4af245d reverted the part of commit de63ab6 (v2.8.0) that made tls_creds and tls_hostname absent instead of "" in the value of query-migrate-parameters, even though commit de63ab6 called that a mistake. What a mess. Drop the redundant tests for presence, and update documentation. Signed-off-by: Markus Armbruster Reviewed-by: Daniel P.
