I'm trying to create a table that points to an external postgres database.

I can run the query fine in the preview window, but when clicking the "create the table" button I get the error "info: WITH not implemented" at the top right of the screen (see screenshot).

Can you please advise how I can work around this?

For reference, here's the query that's being run:

"
with 

delegates as (
select stake_address, pool_address, stake_address_id  from (
select row_number() over(PARTITION BY d.addr_id order by d.addr_id, d.id desc) row_number, sa."view" stake_address, ph."view" pool_address, d.addr_id stake_address_id
from delegation d 
join pool_hash ph on ph.id = d.pool_hash_id
join stake_address sa on sa.id = d.addr_id 
join delegation alldelegations on alldelegations.addr_id=d.addr_id
where 
ph.view='pool1rtj8f2pjedcjh78ey2fc4wvatjyeudeam6lsv6snttwuvhn2vsq'

join tx_out txo on txo.stake_address_id = delegates.stake_address_id
