TBH, I've been wondering about that myself, but never bothered to to
anything about it. Digging in the (now git) history, it's been like
that from the very beginning in 2005:


https://anonscm.debian.org/cgit/pkg-postgresql/postgresql-common.git/commit/?id=9fa563e78366db3b27d680607c202b6fbb00bef2

It got touched a bit when 8.0 support was added, but basically not
changed since then.

I'll see if I can simply remove it. Thanks for the suggestion.
