Either too few parentheses, or too many ;-)
You could write this as an INSERT/SELECT:
insert into table_name (field_name) select setval('sequence_name')-1 as currval;
or you could write it as an INSERT/VALUES with scalar subquery
expression:
insert into table_name (field_name) values ((select setval('sequence_name')-1 as currval));
(all the parentheses are required here). But really you do not need
a subquery for this at all; VALUES is perfectly content with scalar
expressions:
insert into table_name (field_name) values (setval('sequence_name')-1);
