Support multiple occurrences of conditions in the where clause

[s3u]

such as

select * from foo where name = 'foo' and name = 'bar' and name = 'baz'

This should result in a params struct with

name = ['foo', 'bar', 'baz']

Right now, it results in

name = ['baz']

Further, the param name must be substitutable into URIs and request bodies.

But, then

 select * from foo where name = 'foo' and name = 'bar' and name = 'baz' 

will always return nothing, because of the 'and'.

I think we may need a better example to explain the feature.
