Since I encountered encoding issues I skipped upgrading the DB so I used “templates/postgres.9.3.template.yml” instead of “templates/postgres.template.yml”. Now when I try to rebuild I get this:
The following packages will be REMOVED:

0 upgraded, 0 newly installed, 3 to remove and 0 not upgraded.
After this operation, 26.1 MB disk space will be freed.

So I tried to change the line back to “templates/postgres.template.yml” and try with that. However I see this error:

UPGRADE OF POSTGRES FAILED
You are going to need to export your data and import into a clean instance:
In containers/app.yml: Change "templates/postgres.template.yml" TO "templates/postgres.9.3.template.yml"
Run ./launcher rebuild app again
...
...
I tried to enter the docker container to see why the command failed. I run the /usr/lib/postgresql/9.3/bin/pg_ctl ...
command manually, and I saw that the command (which, I think, starts up a new postgres 9.3 server) failed because there was already an instance of postgres 9.3 running. So I tried to stop that instance but, everytime I rebuild
, postgres is automatically restarted.
So I tried to do systemctl disable postgresql
(or update-rc.d postgresql disable
) but it doesn’t work. It just says:
insserv: warning: current start runlevel(s) (empty) of script `postgresql' overrides LSB defaults (2 3 4 5).
insserv: warning: current stop runlevel(s) (0 1 2 3 4 5 6) of script `postgresql' overrides LSB defaults (0 1 6).
but on the next rebuild, postgres is running again.
I can’t get postgres to not run at startup… any ideas?
