copying database?

hi
i have working installation of postgresql 7.2 in one location.
then i have devel machine which should have more or less curent database
on it.
problems:
1. database is > 1gigabytes of data
2. devel machine need r/w access, but all changes to this database has
to be overwritten when downloading new version from working installation
3. i cannot shut down working installation even for a moment.

pg_dump is nto an option - due to time of inserting >1G data into new
database.
i tried to copy DATADIR from working to devel, but it didn't help
(problem with pg_xlog and missing data).

any ideas?
