This applies even if the "-" flag is also specified. So the last

That's very unusual, IMO. This behavior follows some SQL standard or
is it an invention of PostgreSQL?
this is postgresql feature - standard doesn't support any similar
functionality - and printf is some like developer Esperanto. We
significantly reduced complexity of printf function and we modified
basic rules for usage in SQL, but some very typical rules - like format
placeholders, we share - we don't introduce own rules there.
Yes, as I already wrote to Dean (and forgot to cc the list), you are
right, the behavior is correct. Thanks for the explanation!
Kind regards,
