I'd like to do something like this: create table value ( x int4 ) create index on value ( x ) create table filter ( op oid references pg_operator, endpoint int4 ) select value.x from value, filter where value.x filter.op filter.endpoint That is, I want the filter table to specify the operator used in the select (filter.op will be one of the comparison operators for int4). 1. Can this be done? 2. In such a way as to make use of the index on value? -itai
