That's a fair point.  (I assume you mean pg_ctl not pg_init?)

Well, I would have no objection to changing pg_ctl so that it redirects
the postmaster's stdout/stderr when a -l switch is given (actually,
I thought it did that already...).  I do object to changing the logger's
behavior as you suggest, because that will break use-cases that work
today.  One that I've used personally is adding "fprintf(stderr)" calls
in the logger for debugging the logger itself.
