What do you want to achieve? DROP the Primary Key?
ALTER TABLE profile_projectexp DROP CONSTRAINT <constraint_name>;
For instance:
test=# create table foo (id int primary key);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index "foo_pkey" for table "foo"
CREATE TABLE
test=*# \d foo
Table "public.foo"
Column | Type | Modifiers
--------+---------+-----------
id | integer | not null
Indexes:
"foo_pkey" PRIMARY KEY, btree (id)
test=*# alter table foo drop constraint foo_pkey;
ALTER TABLE
