Unable to generate queries using "SET" and "SET LOCAL"

What happened?

I'm trying to generate a query using one of the following variations:

SET LOCAL app.current_user_id = @user_id::text;
-- syntax error at or near "@"

SET LOCAL app.current_user_id to @user_id::text;
-- syntax error at or near "@"

SET LOCAL app.current_user_id = sqlc.arg(user_id)::text;
-- syntax error at or near "."

SET LOCAL app.current_user_id = $1::text;
-- syntax error at or near "::"

SET LOCAL app.current_user_id to cast($1 as text);
-- syntax error at or near "cast"

Eventually, I found that this query works:

SET LOCAL app.current_user_id = $1;

and generates this Go code:

const setSessionUser = `-- name: SetSessionUser :exec
SET LOCAL app.current_user_id = $1
`

func (q *Queries) SetSessionUser(ctx context.Context, dollar_1 interface{}) error {
	_, err := q.db.Exec(ctx, setSessionUser, dollar_1)
	return err
}

Which is not great, but good enough as a workaround.
