Thanks for writing this up. Below are some things I noticed when
reading through (disclaimer: I'm not a native speaker).

"havs" should be "has"

The "using" reads odd to me. I think it would be better either omitted,
or expanded to "when using".

"the ability to use ... is now allowed" doesn't look right. How about
"the ability to use ... is now provided" or "using ... is now allowed"?

"collations for ... collations" doesn't look right. I think either
"comparison for ... collations" or "collation ... for collations" would
be better, but I'm not sure which.

Should be "on inserts and updates".

Should be either "the CREATE ACCESS METHOD command" or just "CREATE
ACCESS METHOD".

> ### Page Checksums
>

Should be "a PostgreSQL cluster", not "an".
