During pg_dump startup, acquire table locks in batches.
Combine multiple LOCK TABLE commands to reduce the number of
round trips to the server. This is particularly helpful when
dumping from a remote server, but it seems useful even without
that. In particular, shortening the time from seeing a table
in pg_class to acquiring lock on it reduces the window for
trouble from concurrent DDL.
