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.
