Can you see the name with \d <table> within psql?
An example:
test=# create table bla (id int check (id between 1 and 4));
CREATE TABLE
test=# \d bla Table "public.bla"Column | Type | Modifiers
--------+---------+-----------id | integer |
Check constraints: "bla_id_check" CHECK (id >= 1 AND id <= 4)
test=# alter table bla drop CONSTRAINT bla_id_check;
ALTER TABLE
test=# \d bla Table "public.bla"Column | Type | Modifiers
--------+---------+-----------id | integer |
