Author Restoring 64 to x86
Benjamin Arai

2005-12-26, 1:23 pm

Are there any compatability issues from dumping a database from a x86
installation and restoring it on a 64bit install or vice versa? I am
assuming I can go from x86 to 64 but I am not sure about the other way.
Any information would be greatly appreciated.

It won't work, in either direction, because of different alignment rules.

Is there a way to transfer data between the two architectures?

I would think you could do it over the network:

pg_dump -U postgres foo|psql -U postgres -h other_machine foo

I thought you said that it would not work in either direction?

Sure: pg_dump. But you can't just move the physical database files,
any more than you could do across completely different architectures.

Hehe, x-mas time ;) He said "dumping" and "restoring" on initial post.
I was wondering too as you said it would not work.

I assumed he was hoping to take a shortcut, but maybe I was overthinking
the question ...
