Is it possible to create a view or foreign table that will do
something like this
select * from table_x

passing the where "x_id = 10" to a function
sorta like this
select * from api_function('x = 10')
or
select * from api_function(10)
passing the result set back to the original select....
your first version of api_function would have to use that x=10 to
construct the query and EXECUTE it, then return the recordset,
your second version of the view would just pass 10 in as an argument,
which could be used for the query select * from table_x where x_id=$1
either way, your view would be select * from api_function(whichever).
but I think you're rather confused here, as I don't see much utility in
either of these constructs in the form you specified.
