Hi,
the pg_checksums docs mention that "When enabling checksums, every file
in the cluster is rewritten".
From IRC discussions, "rewritten" seems ambiguous, it could mean that a
second copy of the file is written and then switched over, implying
increased storage demand during the operation.
So maybe "rewritten in-place" is better, as per the attached?
Michael
