Thread: Pg_upgrade question
We are planning to upgrade to 9.01 from 8.4/8.3 version. On my production Server, there isn't much space left to do a pg_upgrade (Copy),
Can I execute pg_upgrade from new box by pointing to the data directory and binaries on old box.
Thanks
Deepak

Alternatively, you can use pg_dump of 9.0 to dump the data, and restore it using psql, since you don't really need pg_upgrade here -- you will be moving to a new hardware anyway.
