Today I caught this with postgresql v15, while restoring a database with psql --echo-errors --quiet. (The dump was made using pg_dump -Fp).
It logged lots of these messages:
setval -------- 1001 (1 row)
In other words, it logs **some** things that are not errors, even though --quiet was specified. Is this the expected behaviour? I would argue that with --quiet --echo-errors, only errors should be logged, and setting the value of a sequence is not an error.
The output of SELECT queries cannot be quieted, only redirected.
