Llevo dos horas buscando en google sin solucionar el problema. ¿Por qué sucede esto y cómo podría solucionarlo?

Parece que hubo unbichoen los paquetes 9.1, pero debería arreglarse.

Como se indica en el hilo vinculado, el problema podría resolverse ejecutando:

update-alternatives --remove postmaster.1.gz /usr/share/postgresql/9.1/man/man1/postmaster.1.gz

y luego reinstalar postgresql-9.1:

apt-get install -f
apt-get install --reinstall postgresql-9.1
