Comment(by dre@…):

 Replying to [comment:1 dre@…]:
 > It seems this was due to Mr. Zombie having a separate instance of
 postgres running. When he terminated that instance, calendar server was
 able to start its own postgres instance. This requires investigation...

 Have a look at CalendarServer/CalendarServer/data/Logs/postgres.log. This
 hopefully will contain some information about why calendar server's
 postgres instance failed to start. I've got a dollar that says it's kernel
 shared memory limits. If this is true, what you encountered is not a bug,
 but rather a configuration issue, and you can read more about the tunings
 you would need to run multiple instances here:

 Also note that although there is a postgres.conf config file, a couple key
 settings are specified as command line options when calendar server starts
 postgres. They are: -c shared_buffers=30 -c max_connections=20. I mention
 this only because the command line args always take precedence over what's
 in the config file.
