From 97377048b460823a300b1d414203c5f09c8efc1b Mon Sep 17 00:00:00 2001
From: Peter Eisentraut

Subject: pg_cast table, and standards-compliant CREATE/DROP CAST commands,
 plus extension to create binary compatible casts.  Includes dependency
 tracking as well.

pg_proc.proimplicit is now defunct, but will be removed in a separate
commit.

pg_dump provides a migration path from the previous scheme to declare
casts.  Dumping binary compatible casts is currently impossible, though.
