Thread: Migration from 7.4.2 to 8.1.4
Hi!
I'm an administrator of a big company who has a PgSQL-database version 7.4.2. We would like to upgrade it to 8.1.4 but the dump we made cannot be restored. We got a lot of error messages while restoring database related on something's being restored before other objects would exists. ( ??? ) We have made some changes in the dump reversing creation processes and it seems to be useful but there's a lot of error messages on the same problem and do not have time to do them all by hand.
We need help to convert this dump for us ( I can provide binary data if needed ) to be able use it with the new system. We would pay this conversion.
Thanks in advance,
John Gallai,

You should have more success if you use the pg_dump(all) program from 8.1.4 to create the dump. -- Peter Eisentraut http://developer.postgresql.org/~petere/

When upgrading use the newer version (i.e., use 8.1.4's pg_dump against the 7.4.2 database). -- Michael Fuhr

Could you show the exact dump and restore commands you ran and a few of the errors? Are you sure you ran the new (8.1.4) pg_dump or pg_dumpall against the old (7.4.2) database? -- Michael Fuhr
