Back-port a few PostgresNode.pm methods.
The 'lsn' and 'wait_for_catchup' methods only exist in v10 and
higher, but are needed in order to support a test planned test
case for a bug that exists all the way back to v9.6. To minimize
cross-branch differences in the test case, back-port these
methods.
