Psql shows too many parentheses when it prints triggers with WHEN clause.
postgres=# \d t1
Table "public.t1"
Column | Type | Modifiers
--------+---------+-----------
c1 | integer |
Triggers:
mytrig AFTER UPDATE ON t1 FOR EACH ROW
WHEN ((old.c1 <> new.c1)) EXECUTE PROCEDURE myfunc()
^ ^
The attached patch eliminates unneeded parentheses by using
pg_get_triggerdef(pretty = true) in psql.
Triggers:
mytrig AFTER UPDATE ON t1 FOR EACH ROW
WHEN (old.c1 <> new.c1) EXECUTE PROCEDURE myfunc()
I think this change is harmless because we don't use
pg_get_triggerdef(pretty = true) in any programs, including pg_dump.
Is this change ok?
