+
+ Previously, a local query cancellation request did not cause an
+ already-sent remote query to terminate early. This is a back-patch
+ of work originally done for 9.6.

+ Use correct daylight-savings rules for POSIX-style time zone names
+ in MSVC builds (David Rowley)
+
+
+ The Microsoft MSVC build scripts neglected to install
+ the posixrules> file in the timezone directory tree.
+ This resulted in the timezone code falling back to its built-in
+ rule about what DST behavior to assume for a POSIX-style time zone
+ name. For historical reasons that still corresponds to the DST rules
+ the USA was using before 2007 (i.e., change on first Sunday in April
+ and last Sunday in October). With this fix, a POSIX-style zone name
+ will use the current and historical DST transition dates of
+ the US/Eastern> zone. If you don't want that, remove
+ the posixrules> file, or replace it with a copy of some
+ other zone file (see ). Note that
+ due to caching, you may need to restart the server to get such changes
+ to take effect.
