Thanks for pushing the v3 patch.

I'd forgotten about the 'streaming' option -- AFAIK this was
previously a boolean parameter and so its [= value] part can also be
omitted. However, in PG16 streaming became an enum type
(on/off/parallel), and the value can still be omitted but that is not
really being covered by the new generic text note about booleans added
by yesterday's patch.

e.g. The enum 'streaming' value part can still be omitted.
test_sub=# create subscription sub1 connection 'host=localhost
dbname=test_pub' publication pub1 with (streaming);

Perhaps a small top-up patch to CREATE SUBSCRIPTION is needed to
describe this special case?

PSA.

(I thought mentioning this special streaming case again for ALTER
SUBSCRIPTION might be overkill)
