Remove postgresql package's local copy of tzdata files, so it won't need to

be turned for routine timezone updates.

postgresql-use-zoneinfo.patch

@@ -0,0 +1,59 @@
+PostgreSQL includes its own copy of the zic timezone database, which is great
+for ensuring portable results but not so great from a package maintenance
+perspective.  Since the data is in the same format as is provided by the
+Linux-standard /usr/share/zoneinfo files, we can avoid having to update
+postgresql for timezone updates by just symlinking to those files.
+
+It is allegedly desirable for the link in question to be a relative symlink.
+I have strong doubts about this, not least because it requires the horrid
+install-time kluge seen below --- we can't use a simple relative symlink when
+making the temporary installation used for "make check", since that will be at
+an indeterminate location compared to /usr/share.  The actual relative link
+also depends fundamentally upon knowing where the PG datadir will get
+installed, namely /usr/share/pgsql.
+
+And if you thought that was bad, it turns out that RPM has some fundamental
+bugs that make it difficult or impossible to replace a directory with a
+symlink during RPM upgrade.  Rather than risk getting caught in that quagmire,
+we choose to name the symlink something different than its predecessor
+subdirectory.  (This part of the hack could perhaps get undone someday, when
+there is no longer any danger of someone trying to rpm-upgrade from an
+installation that isn't patched this way.)
