"-l logfile" should be read as a recommendation to write to some
logfile, not as the literal text of the command.  I don't think
that putting the log file into the data directory is good practice,
either.

All of this seems to be predicated on the idea that someone would cd
into the bin directory and try to do work there.  I don't understand
why we should regard that scenario as sufficiently probable to justify
contorting PG's behavior to make it fractionally less dangerous.
