Debian's and Ubuntu's packages currently look like this (binary ->
translation domain):
/usr/lib/libpq3.so: libpq3
/usr/lib/libpq4.so: libpq4
/usr/lib/postgresql/7.4/bin/postmaster: postgres-7.4
/usr/lib/postgresql/8.0/bin/postmaster: postgres-8.0
/usr/lib/postgresql/7.4/bin/psql: psql-7.4
/usr/lib/postgresql/8.0/bin/psql: psql-8.0
[similar for all other client binaries)
Without my domain patches, i. e. with upstream's scheme it would look
like:
/usr/lib/libpq3.so: libpq
/usr/lib/libpq4.so: libpq
/usr/lib/postgresql/7.4/bin/postmaster: postgres
/usr/lib/postgresql/8.0/bin/postmaster: postgres
As you see, there is a conflict, so to be able to install both
pacakges at the same time, one translation version had to be picked
and stuffed into a separate -translations package, which both versions
depend on. That's ugly and would cause one version to have some
missing translations, therefore I patched the domains to be
version-specific.
I do think that adopting my scheme at least for libpq really makes
sense. Adopting it for the binaries would not do any harm, but it
might not be conformant to your packaging policy, which I don't really
know. The clashing domains are the only things that prevents the
parallel installation of different major versions, so the question
whether or not you want to adopt it mainly boils down to whether you
want to support parallel server installations.
I am grateful that you did the SONAME change upstream, that relieved
Debian and probably other vendors of much pain. OTOH, the Debian
specific translation domain changes are really simple and don't impose
a significant maintenance overhead, so there is no urgency at all.
Thanks and have a nice day!
