sequence owned by backwards compatability

We were running into problems today when we tried to import a 8.2.4 dump
in a 8.1.5 database. It had to do with the new way of assigning
sequences to colums, which confused 8.1.5 I didn't expect that at the
time of configuration, and currently is down-grading to 8.1.x not an
easy option anymore.

Is there any trick to work arround this issue ? some kind of switch for
backwards compatability ?

have thought of parsing the dump through a convert script to translate
the SET OWNED to an ALTER COLUMN,
but if there may be an easier way to achieve the same result.

thanks in advance,

regards
wouter

No switch but you could restore the schema separately from the data.
Then you could edit the schema to fit 8.1 commands before restore.

Out of curiosity.. why are you doing this? :)

Don't like the idea of manualy editing the schema, seems like a waste of
time, specialy knowing that the situation will pop up more then once

I guess a data only restore will work on existing 8.1.x databases, but
then there is the hassle of truncating tables and disabling/enabling
triggers and all the the other yet unknown trouble.

We are working with multiple configurations from 8.0.x to 8.2.x, its
imposible to upgrade them all at the same time.
Dump and restore of the complete database ..was.. allways the easiest
way to get all data across.

Don't start a new thread by replying to an old one, start a new thread
fresh... Anyway

fc6 is EOLed, you should really look at going to fc7 or 8. But...

just download the redhat rpms from the postgresql site, and in the
same directory as them do something like this:

sudo rpm --install postgresql*rpm

and that should do it.
