Package: postgresql-server-dev-16 
Severity: normal 
X-Debbugs-Cc: loukh...@lotes-tm.ru 

Dear Maintainer, 

I have postgresql-server-dev-16 as a build dependency in my package, minimal 
debian/control file to reproduce the problem is as follows: 

Source: cross-deps-problem 
Build-Depends: debhelper (>= 13.3.4), 
postgresql-server-dev-16 
Section: libs 
Priority: optional 
Standards-Version: 4.3.0 

I'm using official debian:trixie docker image and issuing the following 
commands to prepare build: 

root@e93cc49d3bff:/code/dep-problem-tracking# dpkg --add-architecture armhf 
root@e93cc49d3bff:/code/dep-problem-tracking# apt-get update 
[ mailto:root@e93cc49d3bff:/code/dep-problem-tracking# | 
root@e93cc49d3bff:/code/dep-problem-tracking#  ] apt-get dist-upgrade 
root@e93cc49d3bff:/code/dep-problem-tracking# apt-get build-dep -aarmhf .

Despite that, if I issue `apt-get install postgresql-server-dev-16:armhf` 
command everythins resolves and installs just fine, but `apt-get build-dep 
-aarmhf .` still fails with the following (same) diagnostics:

It is worth to mention, this issue also exists in earlier releases. I'm having 
similar issue with postgresql-server-dev-15 in bookworm, but it is failing with 
another dependencies: 

root@f4a15821be16:/code/dep-problem-tracking# cat /etc/debian_version 
12.4

11.8

Please help me to diagnose and resolve this issue at least, in bookworm...
