postgres-xc-general Mailing List for Postgres-XC

Are there any other process which are using the socket?  Probably
another postgreSQL or postgres-xc instance?

If not, it seems that unix domain socket is left.   If you're sure
that no such process is alive, you can just remove this file to fix
the issue.

If you're running both coordinator and datanode or more than one of
them at the same server, you must assign different port number to them
to avoid resource conflict.
