[gentoo-user] pg_upgrade from 9.0.5 to 9.1.1

[Michael George]

I am trying to upgrade my postgresql server from 9.0 to 9.1.  I've
installed 9.1.1 and used eselect to make it the slot to run for the
system.

When I run:
pg_upgrade -v --check -d /var/lib/postgresql/9.0/data -D \
/var/lib/postgresql/9.1/data -b /usr/lib64/postgresql-9.0/bin -B \
/usr/lib64/postgresql-9.1/bin

I get:
Running in verbose mode
Performing Consistency Checks
-----------------------------
Checking current, bin, and data directories                 ok
Checking cluster versions                                   ok
"/usr/lib64/postgresql-9.0/bin/pg_ctl" -w -l "/dev/null" -D
"/var/lib/postgresql/9.0/data" -o "-p 5432 -c autovacuum=off -c
autovacuum_freeze_max_age=2000000000" start >> "/dev/null" 2>&1

When I run that command manually and send the output to a logfile, it
appears that it's trying to find postgresql's *.conf files in the data
directory rather than in /etc/postgresql-9.0.  I don't see a way to
specify the location of the conf files separate from the data files.

How do I proceed?
