Hi Bertrand-san, Michael-san,

Thanks for the feedback.  Centralizing the explanation and linking
from views makes sense, so v2 takes that approach.

Specifically, v2:

  * Adds a new "Fast-Path Locking" subsection under Explicit Locking
    (13.3.1.1, inside Table-Level Locks).

  * References the new section from:
      - pg_stat_lock.fastpath_exceeded  (monitoring.sgml)
      - pg_locks.fastpath               (system-views.sgml)
      - max_locks_per_transaction       (config.sgml)

Patch v2 attached.

Regards,
Tatsuya Kawata
