Since database connections can be used with WAL senders in 9.4, it is
possible to use physical replication. This commit fixes a crash when
starting physical replication with a WAL sender using a database
connection, caused by the refactoring done in 850196b.
There have been discussions about forbidding the use of physical
replication in a database connection, but this is left for later,
taking care only of the crash new to 13.
While on it, add a test to check for a failure when attempting logical
replication if the WAL sender does not have a database connection. This
part is extracted from a larger patch by Kyotaro Horiguchi.
