oops, that's my oversight from copying the message from vacuum. fixed.

good point.
Below is the new output with the attached v2.
postgres=# create index foo_idx1 on foo(id); DEBUG: building index "foo_idx1" on table "foo" with parallel workers DEBUG: launched 1 parallel workers for index creation (planned: 1) DEBUG: index "foo_idx1" can safely use deduplication CREATE INDEX
I tend to agree it might be better than Benoit's patch on the index messages, though I'm afraid that DEBUG1 level won't work for many users. DEBUGx are for developers, not users. A better log level for me would be LOG. For client messages, LOG messages won't be displayed by default. So there's still a need for a "SET client_min_messages to LOG" but it won't be necessary to go all the way to DEBUG1.
