I have some comments.
- No harm, but it's pointless to feed MyLatch to WaitLatch when
WL_LATCH_SET is not set (or rather misleading).

LGTM. The pre/post_auth_delay parameters seem to work as intended,
and they are responsive to postmaster crashes. I didn't find any
examples of calling WaitLatch() without WL_LATCH_SET, but the function
appears to have support

Thanks. IMO, the following looks better:
Waiting on connection startup before authentication to allow
attaching a debugger to the process.

Hi,
As suggested in [1], starting a new thread for discussing $subject
separately. {pre, post}_auth_delay waiting logic currently uses
pg_usleep which can't detect postmaster death. So, there are chances
that some of the backends still stay in the system even when a
postmaster crashes (for
