Hi,

is it safe to move the PGDATA directory from one system to another when migrating from one operating system to another?
For example: migrating from Debian to RHEL, or from RHEL4 to RHEL5?
The database is of course shutdown properly, and the PG major versions match.

Or is a dump/restore necessary in these cases?

Thanks,
 Martin
