If "pg_ctl start" is invoked directly from a command prompt, it works.
Now, if I run "pg_ctl start" within a script (in an msysgit
environment for example), pg_ctl fails, complaining that
postmaster.pid already exists. The TAP tests get broken as well,
attached are the log files of the run, and here is an interested bit:
# Running: pg_ctl start -D

Registering a service to the SCM works, but the service registered
refuses to start.
