CURRENTE_DATE

Hello ,

I am new with PostgreSQL and I have a bug. I have created a function that has an input variable of type date , in case it does not receive value , it has to assume by default the current date.

I have defined it as follows variable  DATE DEFAULT CURRENT_DATE, but I get the following error.

El error

ERROR: invalid input syntax for type date: “CURRENT_DATE” LINE 1: ...extsupplydate ('1085018'::bigint, '5278'::bigint, 'CURRENT_D... ^ ERROR: invalid input syntax for type date: “CURRENT_DATE” SQL status: 22007 Characters: 78

Please could you help me, thank you very much.
