I have succeeded in making OR clauses use indexes. I have not dealt
with some of the more complex issues like x=3 or y=5 as Vadim mentioned,
but at least it works.
test=> select * from test where x=102532 or x=102533;
x
------
102532
102533
(2 rows)
test=> explain select * from test where x=102532 or x=102533;
NOTICE: QUERY PLAN:
Index Scan using i_test on test (cost=4.10 size=1 width=4)
