Обсуждение: pgsql: Tweak the behavior of log_duration as proposed by Guillaume Smet:

Log Message:
-----------
Tweak the behavior of log_duration as proposed by Guillaume Smet: rather
than being equivalent to setting log_min_duration_statement to zero, this
option now forces logging of all query durations, but doesn't force logging
of query text.  Also, add duration logging coverage for fastpath function
calls.
