[Debian-astro-maintainers] Bug#984555: Lowering severity for 2.3+dfsg-3

[Ole Streicher]

Control: severity -1 normal

I just uploaded version 2.3+dfsg-3. This version restricts the 
postgresql related dependencies to postgresql-13, which makes the 
package installable on Bullseye.

As discussed by Markus, this however does not solve the problem 
completely; therefore only the severity is reduced.
