has_pk(:schema, :table) Not defined

[aklaver]

Postgres 14.2
pgTAP 1.2.0

--Schema and no description
SELECT has_pk('utility', 'eqpt_model_info');
not ok 3 - eqpt_model_info
# Failed test 3: "eqpt_model_info"

--No schema and no description
SELECT has_pk('eqpt_model_info');
ok 3 - Table eqpt_model_info should have a primary key

--Schema and explicit description
SELECT has_pk('utility', 'eqpt_model_info', 'test desc');
ok 3 - test desc

This seems to run counter to the docs:

If the test description is omitted, it will be set to “Table :table should have a primary key”.

All right some time in pgtap.sql.in showed me what is going on. Due to function overloading the only form that automatically sets the description is has_pk( :table ). I was misunderstanding and thought :description was optional in all cases. I now know that the function signatures need to be fully followed for the different forms.

Oh well perhaps we're missing has_pk(:schema, :table). If we had it you could make sure it's called instead of has_pk(:schema, :desc) by specifying the type:

SELECT has_pk('utility', 'eqpt_model_info'::name);

Yeah, I could see that being helpful. Would that fill in the missing :desc like SELECT has_pk('eqpt_model_info');?

Would that fill in the missing :desc like SELECT has_pk('eqpt_model_info');?

Yes, exactly.

Thanks.
