Absolutely. Go ahead right now.
Note that you can use the CONCURRENTLY option to create index, and it will not require a lock on the table, so you can do it while the db is being used. It takes longer, sometimes a lot longer, than the regular create, but who cares? Start it and leave it.
After you’ve done that and seen how much benefit you get just from indexing your most-commonly used column, post a range of common queries back here for further advice.
