That seems a bit bizarre to me. The facility isn't a new log
destination; what it is is a different way of formatting what's
sent to the log.

I think what you'd probably really want to write is something like
log_message_format = 'INSERT INTO mytab VALUES(%this, %that, ...);'
the point being that otherwise we'll need yet another GUC var to determine
the table name used in the INSERT. With a suitable set of escape codes
we could probably arrange for the existing behavior to correspond
to a particular value of log_message_format, and then there isn't
anything weird going on here; you are just changing away from a default
format.
I wonder whether this could be defined in a way that lets it replace
log_line_prefix ... otherwise we have to think about the interaction of
the two facilities.
