Simply name the table constraints yourself with a descriptive name, so you
always know exactly what is going on:
greg=# create table unitest(a int, b text);
CREATE TABLE
greg=# alter table unitest add constraint "unitest_column_a_is_not_unique" unique(a);
NOTICE: ALTER TABLE / ADD UNIQUE will create implicit index "unitest_column_a_is_not_unique" for table "unitest"
greg=# insert into unitest (a) values (1);
INSERT 0 1
greg=# insert into unitest (a) values (1);
ERROR: duplicate key violates unique constraint "unitest_column_a_is_not_unique"
