These sound weird since markup was added in 6a5bde7d4:

"disabled" sounds like it was set to "off". Maybe say it was ignored.
> Add long-running queries to be canceled if the client disconnects (Sergey Cherkashin, Thomas Munro)
Should say: Allow

automaticallycancel queries by disconnected clients.
say "some operating systems" ?
> This can be disabled by turning client option "sslsni" off.
"turning off"
| Add %P to log_line_prefix to report the parallel group leader (Justin Pryzby)
Maybe it should say "Allow %P in log_line_prefix to ...", otherwise it sounds
like the default was changed.
| Reduce the default value of vacuum_cost_page_miss (Peter Geoghegan)
| This new default better reflects current hardware capabilities.
Also say: the previous default was 10.
