I have a projects table that includes these two columns:

start_date date DEFAULT CURRENT_DATE,
end_date date
    CONSTRAINT valid_start_date
    CHECK (start_date <= end_date),

  1. Do I need a DEFAULT value for the end_date?

no, you can use NULL, for instance. You don't need an explicit value.
But maybe you want to set the start_date to NOT NULL.

2. If so, please suggest a value for it.

other solution for such 2 fields: you can use DATERANGE, only one field.
