+      Remove support for posixrules files in the
+      timezone database (Tom Lane)
+     
+
+     
+      IANA's timezone group has deprecated this feature, meaning that it
+      will gradually disappear from systems' timezone databases over the
+      next few years.  Rather than have a behavioral change appear
+      unexpectedly with a timezone data update, we have
+      removed PostgreSQL's support for this
+      feature as of version 13.  This affects only the behavior
+      of POSIX-style time
+      zone specifications that lack an explicit daylight savings
+      transition rule; formerly the transition rule could be determined
+      by installing a custom posixrules file, but
+      now it is hard-wired.  The recommended fix for any affected
+      installations is to start using a geographical time zone name.

+        This behavior is normally preferable to the old behavior.  But if
+        it is inferior for a particular query, behavior similar to
+        previous Postgres releases can be obtained by
+        increasing hash_mem_multiplier.
