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?
