The problem is that in this case, pg_ctl gets the path:
(not unbalanced quotes). Yes, win32 commandline quoting is horrible.
Anyway. then it properly quotes this for the commandline:
and you can see where that breaks down...
Another option would be simple check to simply strip the " (and the
trailing backslash too, probably, to make things safer at the next
step). I just thought it'd be cleaner to use canonicalize_path(). But
it's just the trailing quote stuff that causes the problem. (See the
second step in canonicalize_path() where this has been noticed befoer,
followed by the trim-trailing part which would also be nice).
(Everything works if you register it as a service because then it uses
pg_data and not pgdata_opt. This is just when you start things manually,
which is why we missed it before...)
