I never did `make check'... It is obvious that you already installed
PostgreSQL, did you? But you did not create a database role `edrx',
which is not a must, however, that is what maybe `make check'
expected.

You could simply do it:

$ createuser edrx

In general, you will need to know how to create a role, user or
database before using the database;

$ createdb DATABASE

$ createuser USERNAME

Let us say you created username edrx and database name edrx (you can
have many databases):

Then you do something like:

$ psql

grant all on database edrx to edrx;

it will tell:
GRANT

which means you gave permission to user edrx to use the database edrx;

To learn about psql interface, try \?
