Hi, i was running sql-ledger on redhat 9, then I upgraded to fedora core 3
and postgresql 7.4.6.
Now there's an error message saying "you need to upgrade data format
before using postgresql"
On webpages like
http://www.postgresql.org/docs/7.4/static/install-upgrading.html
There's advice how to backup databases and then upgrade postgresql, but is
the procedure the same when postgresql already has been upgraded, or is
there a special "rescue" procedure ?
Kind regards
Uffe A. Fredens
