Use functions or expressions in Postgres alias names - possible?
Is it possible to use functions or expressions to create an alias name?
For example, is there a way to use concat like this?
SELECT
id."myamazingrecords"
FROM
records AS CONCAT("my", "amazing", "records")
I'm looking for a general way to programmatically (via SQL) rename columns in the output of my query.

No, an alias has to be a literal.
You can either construct the alias in client code before you send the query to the server, or you use a PL/pgSQL function that executes a dynamic query like
EXECUTE format('SELECT id."myamazingrecords" FROM records AS %I',
CONCAT('my', 'amazing', 'records'));
