Tom,
I used:
pg_dumpall > db.out on my 7.4.2 server
Then, I use: psql -f db.out postgres on my 8.1.4 server.
I got chunk of:
1232133 invalid command \N
1232134 invalid command \N
I found that come from my inheritant table, the pg_dump(all) didn't make
right order on parent and child tables, it dumped child tables first
then parent table, so I restore them, it try to create child table first
which will fail definitely then all the data try to be loaded later on
will be errored out. I am not sure 8.1.4's pg_dump(all) fixed this bug
or not. Currently, I think I can work around it by editing the order on
archive.list file and use pg_restore.
Best Regards,
Jie Liang
