Comment 18 for bug 235379

I had to delete some directories after purging, then reinstallation worked. I deleted:

rm -rf /usr/lib/postgresql/8.3/lib /usr/share/postgresql/8.3/tsearch_data /usr/lib/postgresql/8.3 /usr/lib/postgresql /var/lib/postgresql

Probably just that first directory had to be deleted. After reinstalling it all worked.
