[Pkg-postgresql-public] Bug#764705: postgresql-9.4: ERROR: The database format changed between beta 2 and 3. Please dump, but how?

Package: postgresql-9.4
Followup-For: Bug #764705

Dear Maintainer,

I, like a previous poster, have this:

postgres at deblack:~$ pg_lsclusters
Ver Cluster Port Status Owner    Data directory               Log file
9.3 main    5432 online postgres /var/lib/postgresql/9.3/main /var/log/postgresql/postgresql-9.3-main.log
9.4 main    5433 online postgres /var/lib/postgresql/9.4/main /var/log/postgresql/postgresql-9.4-main.log

which means I have both 9.3 and 9.4 installed. Thus, I was a little
worried about the command 

	$ zcat 9.4-main.dump.gz | psql -q

in the instructions -- there was no mention of 9.4 in the dump file,
and by default, psql connects to the 9.3 server; thus, I think that
if I had run the command as given, it would have applied to the 9.3
cluster and not the 9.4 one.

I ran it instead as 

	$ zcat 9.4-main.dump.gz | psql -p5433

(9.3 runs on 5432, 9.4 on 5433). If I'm wrong, I'd love to be told
about it; otherwise, I suspect the instructions should be modified.

Thanks,
Shai.
