Today, pg_migrator 8.4 final is released. The code has gone through
many betas and has been completely overhauled since its last major
release in 2007. It supports migration from Postgres 8.3 to 8.4 without
a data dump/reload.
pg_migrator is designed specifically for experienced users who have
large databases, where a data dump/restore burdensome. You can download
