There must be a significant difference between this: select 'dog'
and this: (select 'dog')
This works fine: select length( (select 'dog') )But without the doubled parentheses, it causes a syntax error.
On the other hand, an extra pair of surrounding parentheses here select array( (values (17), (42)) )while not necessary, *is* tolerated.
