lockdefs.h is much younger (4eda0a64705763854225a29703b606692af50e77)
than the comment (b153c0920960a6059b67969469166fb29c0105d7) mentioned
above. The commit changed some #include "lock.h" to use lockdefs.h. I
guess it didn't notice that parse_relation.h can use it because it
didn't include lock.h and didn't define LOCKMODE. The change looks
good to me.

Not needed.
