This is looking crisper. Nice edits! I did one more read through and have minor comments and suggestions.
----------------------
> "PostgreSQL 17 introduces a new internal memory structure for vacuumwas used that consumes up to 20x less memory"Small typo, I think "that" was missed:PostgreSQL 17 introduces a new internal memory structure for vacuum that consumes up to 20x less memory.
----------------------
> "and PostgreSQL 17 adds to its implementation SQL/JSON standard."
is this missing "of the" ?
and PostgreSQL 17 adds to its implementation "of" the SQL/JSON standard.
----------------------
"exporting,including"
add space after "exporting", assuming this was copied correctly from the source file into google docs (which it may not have been) :)
----------------------
This is in the realm of personal preference/suggestion. The word "federated" is complex and I kind of understand it, but prefer simpler terminology. Here's a suggestion:
"This release expands on functionality for managing data in partitions or
federated on remote PostgreSQL instances."
Alternative: "This release expands on functionality for managing data in partitions or data spread out between local and remote PostgreSQL instances."
----------------------
Suggestion: both "converts" and "creates" verbs are used in the docs to describe pg_createsubscriber. I like the verb "convert" because I think it speaks more to the purpose of being run on a physical replica, then turning it into a logical replication based instance as a subscriber.With that said, my suggested alternative is:PostgreSQL 17 introduces the[`pg_createsubscriber`](https://www.postgresql.org/docs/17/app-pgcreatesubscriber.html)command-line tool which can be used to convert a physical replica into a logical replica.
----------------------
> "which allows you to give users permission to execute maintenance operations."
Suggested simplifications:
which gives users the permissions needed to perform maintenance operations.
which provides permissions for maintenance operations.
----------------------
----------------------
----------------------
"Many other new features and improvements have been added to PostgreSQL 17. Many
of these may also be helpful for your use cases."
Recommend consolidating these two sentences.
----------------------
"## Licence" is the british english spelling intended here?
----------------------
Looks great! I even learned about more new features in this revised version! I checked the links and saw "17" everywhere I'd expect to see it.
