Hi,

I have two tables which have an identical column and their indexes are
based on this column.  I am trying to do a join on these two tables, but
it takes forever for postgresql to join these two tables.

The command i'm using is:
select * from icpr,iprc where icpr.prod_no='23' AND
icpr.prod_no=iprc.prod_no;

Can anyone tell me what I'm doing wrong?  I've tried to cluster both
tables based on their indexes, but it's still extremely slow..

Any help would be greatly appreciated,

Mike
