Yet that is what we get for `pg_config --version' on the
affected system. A nearly identical error message seems to
come up while installing psycopg2 -- a Python library for
Postgres, e.g.:

I have not the slightest idea why pg_config should print
this message, unless it is not a genuine pg_config. I will
be checking its binary against the one that works as expected
on our reference system.

Do you mean 8.3.0-6? It looks like the GCC version. Our
Astra is 1.7.5:

ant(at)xx:~$ cat /etc/issue
Astra Linux 1.7.5 \n \l
