Subject: [PATCH] PG18: use data-checksums by default in upgrades (#8230)

Checksums are now on by default in PG18: 04bec894a

Upgrade to PG18 fails with the following error:
`old cluster does not use data checksums but the new one does`

To overcome this error, we add --data-checksums option such that
clusters with PG less than 18 also use data checksums.

Fixes #8229
