I believe this is the expected output for a table with 56 rows and zero
columns. (It's probably a bug that psql doesn't display that as 56
empty lines, but nobody's cared enough to fix it.) Since you did not
include anything in "select", you've got a zero-column result table.

You didn't say what query results you expected to get, but it's hard
to see how you get anything but zero columns from this query.
