> I think DEBUG is perfectly appropriate for this sort of message.
I am curious what are the thoughts on introducing a CREATE INDEX VERBOSE which can provide this info? similar to users scripting VACUUM VERBOSE to log more details about the vacuum operation including parallel usage.
I have not convinced myself this is a good idea, but maybe someone has an opinion. If not, we can just stick with a better DEBUG1 message.
Sounds better to me than relying on DEBUG messages. So, yeah, VERBOSE has my vote.
