I suspect it's picked up here: VERSION=${0: -12:4}
I don't know what is the real full name of the maintainer script here,
but I think it's not what you think.

[10:35] <XTF> jcristau:  VERSION=${0: -12:4} this code tries to
extract the version number from "mariadb-server-10.3.preinst" but it
seems to get "p.ci" instead.
[10:36] <jcristau> that code shouldn't make that sort of assumption
[10:36] <XTF> jcristau: I agree..
[10:37] <Myon> there should be DPKG_* variables with that info
[10:37] <jcristau> preinst runs from somewhere in /tmp
[10:37] <Myon> iirc DPKG_MAINTSCRIPT_PACKAGE
[10:38] <jcristau> right, what Myon says
[10:38] <Myon> https://salsa.debian.org/postgresql/postgresql/blob/11/debian/postgresql-11.preinst#L5
[10:39] <XTF> Thanks, I'll copy that info into the bug report.
