[Pkg-postgresql-public] Bug#719282: installing dictionary package restarts postgresql servers

[Peter Eisentraut]

Package: postgresql-common
Version: 147.pgdg70+1
Severity: normal

Installing a dictionary package, for example apt-get install
hunspell-de-de, ends up restarting all PostgreSQL servers on the
machine, because the dictionary trigger calls postinst, which restarts
everything because of the way debhelper sets this up.  I think that's
a fairly radical reaction.

This might be more general problem.  Maybe a fix in debhelper is
needed?
