Creating a view might work.
Yeah, if all you use is SELECT, you should probably use a view, then you
don't need to specify the output columns in the calling statement, only a
WHERE clause.
Othrewise, it's the same thing:
SELECT * FROM myview WHERE field1=10;
Views are transparant in postgresql, so you need not worry that at first
your backend will load the whole view and then filter your results
(performance-wise).

What do these tables join on?
Creating a view might work.
CREATE VIEW V_SIDE_BY_SIDE AS
SELECT T1.*, T2.*
FROM TABLE1 T1,
TABLE2 T2
WHERE T1.PK = T2.PK;

choose an index scan if your joining column's datatypes do not
match
