I saw this was marked ready-for-committer, so I took a look at the thread.
It looks like there are two ideas:
* Separate log_lock_waits from deadlock_timeout. It looks like this idea
has a decent amount of support, but I didn't see any patch for it so far.
IMHO this is arguably a prerequisite for setting log_lock_waits on by
default, as we could then easily set it higher by default to help address
concerns about introducing too much noise in the logs.
* Set log_lock_waits on by default. The folks on this thread seem to
support this idea, but given the lively discussion for enabling
log_checkpoints by default [0], I'm hesitant to commit something like
this without further community discussion.
