pg_upgrade: Fix some minor code issues

petere · petere · commit 08c5c6d2833b · 2022-08-13T00:14:49.000+02:00
96ef3b8 accidentally copied a not applicable comment from the float8_pass_by_value code to the data_checksums code. Remove that. 87d3b35 changed pg_upgrade to checking the checksum version rather than just the Boolean presence of checksums, but didn't change the field type in its ControlData struct from bool. So this would not work correctly if there ever is a checksum version larger than 1.
