The first statement just generates a line of text output that contains the statement.  There's nothing in it that would cause that statement to be executed.

If you want to create a statement dynamically and then execute it, you can do that with pl/pgSQL:

        https://www.postgresql.org/docs/current/plpgsql-statements.html#PLPGSQL-STATEMENTS-EXECUTING-DYN

Otherwise, the solution is to do as you did: write the output to a file, trim out any extraneous lines, and then use that as a script.

Or in psql execute it using the \gexec meta-command instead of a semi-colon.
