does ksqldb support the create or replace for a stream?

I got to this by reading some stackoverflow post about how to redefine a stream if in time it changes. I was looking and end up in this PR: https://github.com/confluentinc/ksql/pull/5611

It seems in theory that it should but if I just look at the documentation I could not find it https://docs.ksqldb.io/en/latest/developer-guide/create-a-stream/

Now I'm trying it in my ksqldb and I'm getting an error:

ksql> CREATE OR REPLACE STREAM obj_pos_proto (id INT, obj_type_id INT) WITH (KAFKA_TOPIC='obj_pos', VALUE_FORMAT='PROTOBUF');
line 1:8: no viable alternative at input 'CREATE OR'

is the only way to have this working to drop and then create again?

It does not currently support it. The github merge that you saw is the design document (KLIP) - the actual functionality has yet to be added. There is a lot of work underway in this area though, so stay tuned!
