Postgres removing old database
Recently, I upgraded from Postgres 6.5.3 (stable Debian) to Postgres
7.0 (unstable). During the installation, it didn't ask me anything,
besides overwriting the config files. Instead it gladly removed all my
databases which were in /var/lib/postgres/data/base/.
Luckily, I had made a dump myself, prior to the upgrade, so there was
no problem getting them back, but it would've been a good idea to have
it dump and restore the databases itself. I can remember an older
upgrade of postgres (6.0 -> 6.5 perhaps?) doing just this, so I wonder
why this didn't.
