I think I have the same problem, I can't uninstall postgres-xc. It says:
postgres-xc: subprocess installed pre-removal script returned error exit status 1

In the details it says:
Removing postgres-xc ...
 * Stopping Postgres-XC datanodes [OK]
 * Stopping Postgres-XC coordinators >> [fail] <<
invoke-rc.d: initscript postgres-xc, action "stop" failed.

It looks like it can't stop the coordinators ...

Thanks,
V.

Status changed to 'Confirmed' because the bug affects multiple users.

sudo apt-get --purge postgres-xc Fails

[linuxlab (linuxlab-nz)]

work around for now, so to continue installing other packages and apt-get not get jammed

$ sudo apt-get install -m <new package>

will skip the failed postgres-xc problem and carry on installing desired package. IE: <new package>

I manually removed the postgres-xc folder from usr/share. Then I attempted both...

$ sudo dpkg --purge postges-xc

followed by
$ sudo apt-get remove postgres-xc

then repeated the first command.
All returned the same error: "invoke-rc.d: initscript postgres-xc, action "stop" failed."

The postgres-xc folder is still absent. Entering "$ sudo initdb -D /usr/local/pgsql/data" continues to return the "initdb: Postgres-XC node name is mandatory" error.

As far as I can get, Postgresql is still unusable for me.

Hi

A work around that is fine to remove postgres-xc is:

sudo vim /var/lib/dpkg/info/postgres-xc.prerm

Add "exit 0" after first line (#/bin/sh -e)

It works!
