This is a normal error.
If you want to remove the sequence first you have to remove the default
value from the sequenced field.
remember serial means int4 with a default of get next serial number.
ALTER TABLE test
ALTER COLUMN test_id_key DROP DEFAULT;
After that you could probably drop the sequence without a problem
