Can I activate PITR after the DB has been used

Problem
My Postgres-Server is running for quite a while and contains probably 4-5 GB of data.
Backups are done using dumps, and this works ok. Though not most efficient, it just works.
Due to future growth I like to activate PITR backups (like RMAN in Oracle).
Is that possible and/or recommended? Or would it be better for me to recreate the DB with the correct settings upfront?

Solution
No need to recreate the database. Set up
It is quite common to "upgrade" from pg_dump to PITR backups as the database grows.
archive_mode and archive_command, restart the server, create a base backup, and there you go. (Details vary depending on version.)It is quite common to "upgrade" from pg_dump to PITR backups as the database grows.
