pg_upgrade and ubuntu

I ran into an issue migrating from 9.1 to 9.3 on ubuntu using pg_upgrade

the default ubuntu package, and the one from postgresql.org, both store `postgresql.conf` in etc as `/etc/postgresql/VERSION/main/postgresql.conf`

however, the pg_upgrade script expects it in the `datadir`.

the simple solution seems to be just symlinking the /etc files into the data dirs.

it took me a while to realize this was the error.

it might make sense to upgrade the docs with a note about what should be in the data dir to enable an upgrade.

It would make more sense for the Debian packagers people to write a
pg_upgradecluster wrapper like they have done for the other key programs.

I believe there is:

http://www.postgresql.org/docs/9.3/interactive/pgupgrade.html

Notes

"If you are upgrading a pre-PostgreSQL 9.2 cluster that uses a
configuration-file-only directory, you must pass the real data directory
location to pg_upgrade, and pass the configuration directory location to
the server, e.g. -d /real-data-directory -o '-D /configuration-directory'."

Note it appears there is a pg_upgradecluster program, but it doesn't appear
to a wrapper for the official program...

As far as I recall, pg_upgradecluster goes through a pg_dump /
pg_restore cycle. It predates pg_upgrade itself.

<should finish skimming before I post things....>

Anyway, without self verification, it appears from here:

https://bugs.launchpad.net/ubuntu/+source/postgresql-common/+bug/939260

that you can instruct pg_upgradecluster to use the official program to do
the upgrade instead of its old method - whatever that was...

On Debian/Ubuntu, use pg_upgradecluster --method upgrade. See the man
page for details.
