I've seen the thread you started with a similar problem, and it has
been useful to solve the problem with the concrete database, but my
problem is that we host 20 different databases (and growing)for hosting
clients and we don't know who's using OID's and who's not.

I think that the Chapter 9.3 (Migration between releases) would have to
concrete that the OIDs doesn't work with the method explained (despite
pg_dumpall has the -o option) and how to make the migration process in
this case.

I have not encoutered too much documentation about it, and finally I've
followed this process (could be useful for someone):

1.-Search the databases having OIDs ( \dl command on each one), this is
easy to automate via shell script ( but I did'nt make it).

2.-With the pg_dumplo utility (contrib directory), backup the OID
objects for each database discovered in 1

../../pg-7.4.3/bin/pg_dumplo -s /tmp/dumpoids -d database_name -e

3.-Run the pg_dumpall

../bin/pg_dumpall -o -c -p 5432 | /apps/pg-7.4.3/bin/psql -d template1
-p 5433 1>/tmp/sortidaimport 2>/tmp/sortidaerror

4.-Import the OIDs to the new postgres using pg_dumplo (for each
database with OIDs)

../../pg-7.4.3/bin/pg_dumplo -s /tmp/dumpoids -d pragenda -o 5433 -i

It worked for me ...

If anyone knows a better, faster or automatic process to perform the
upgrade I'll be pleased to know it ...

And sorry for my poor english ...
