Thank you. That is I am looking for.
Never thought that 'WITH' syntax is described at 'SELECT'. 

Will be very helpful if this will be mentioned on this page: https://www.postgresql.org/docs/10/static/queries-with.html
For an example:

       [ WITH [ RECURSIVE ] with_query [, ...] ]

and with_query is shown as:

       with_query_name [ ( column_name [, ...] ) ] AS ( select | values | insert | update | delete )

For full syntax of `WITH` see https://www.postgresql.org/docs/10/static/sql-select.html


Thanks.
