Fast or immediate shutdown
running with log_checkpoints = on
pg_ctl -D foo -m fast stop
log says
LOG: received fast shutdown request
LOG: aborting any active transactions
LOG: shutting down
LOG: restartpoint starting: shutdown immediate
Some of us know that the "immediate" word refers to the restartpoint
request, though that word causes conceptual conflict with the shutdown
mode, which was fast, not immediate.
Think we need to change the wording of this
LOG: restartpoint starting: shutdown immediate
so it is clearer what we mean

We could insert the words "with flags" just before the colon, I suppose.

We *do* we mean? And why are we logging it?

The words after the colon refer to options sent to RequestCheckpoint and
it is logged because we asked for it by doing log_checkpoints = on.
I suggest we say "smoothed" when checkpoint option is !immediate. So we
will remove the word "immediate" from the message.

The opposite of smooth could be sharp. :)

Personally, my opinion is that if we're going to print the message at
all, the names used for the message should match the names used in the
code. So -1 from me on calling it immediate in the code but smoothed
in the message. On the other hand, I have no personal attachment to
that message, so if other people feel it's not needed at all, I could
see removing it.
