We can output this at the LOG level to avoid running the server at
DEBUG1 level. There are a few other cases where we are not able to
spawn the worker or process and those are logged at the LOG level. For
example, "could not fork autovacuum launcher process .." or "too many
background workers". So, not sure, if this should get a separate
treatment. If we fear this can happen frequently enough that it can
spam the LOG then a GUC may be worthwhile.

I think it could be easier for users to process the information if it
is available via some view, so there is a benefit in putting this into
the stats subsystem.
