Does it matter when writing SQL code in PostgreSQL if I use DECIMAL or
NUMERIC date types for a column named 'price' assuming it's to store
the associated items actual dollar amount?

Reading the fine manual*, I can't find a single difference between
either and they both are supported / recognized by PostgreSQL:

-decimal        variable        user-specified precision, exact         up to 
131072
digits before the decimal point; up to 16383 digits after the decimal
point
-numeric        variable        user-specified precision, exact         up to 
131072
digits before the decimal point; up to 16383 digits after the decimal
point

CREATE TABLE computers
(
id serial primary key,
make varchar(50) not null,
model varchar(50) not null,
owner varchar(50) not null
price decimal(7,2) not null,
warranty date not null
);
