Something like "CREATE VIEW"? The documentation has some useful
examples: https://www.postgresql.org/docs/current/sql-createview.html

"CREATE PROCEDURE" and "CREATE FUNCTION" are rarely covered by
tutorials, so I mention them. They can be used in a similar manner.


For CSV, I'm the wrong person. I'd code it in C/C++.
