Bug#1121958: libdbd-pg-perl: autopkgtest regression: Invalid initdb

[Paul Gevers]

Source: libdbd-pg-perl
Version: 3.18.0-2
Severity: serious
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainer(s),

Your package has an autopkgtest, great. However, it started failing 
somewhere mid November 2025 in testing. Earlier pseudo-excuses runs in 
unstable started failing before then, those were mostly combined 
triggers. Can you please investigate the situation and fix it? I copied 
some of the output at the bottom of this report. I used 
packages.debian.org to query for "bin/initdb" and it seems that 
postgresql-18 ships it in a directory with the psql version number: 
/usr/lib/postgresql/18/bin/initdb

The release team has announced [1] that failing autopkgtest on amd64 and 
arm64 are considered RC in testing.

More information about this bug and the reason for filing it can be
