I have just thought about a possible problem with this plugin. Indeed, using it makes the startup of the Orthanc service dependent on the startup of the PostgreSQL service: Orthanc will crash if it started after PostgreSQL.

It would therefore be logical to modify the "/etc/init.d/orthanc" file [1] by applying the patch attached to this mail. However, this dependency cannot be added inside the main "orthanc" package, as PostgreSQL is not a dependency of the default version of Orthanc (that internally uses SQLite).

Could someone tell me how this case could be handled? Should the "orthanc-postgresql" package patch "/etc/init.d/orthanc" from "postinst" and un-apply the patch from "postrm"?

Thanks,
