Hi,
When I read the documentation of pg_waldump, I found the description about
-B option is wrong.
-B block
--block=block
Only display records that modify the given block. The relation must also be provided with --relation or -l.
Before 52b5568, the -l option is short for --relation, however, it has been
changed to -R, and we forgot to update the documentation.
Here is a patch for it.
