From 0b03e5951bf0a1a8868db13f02049cf686a82165 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Fri, 7 Nov 2014 17:26:02 -0500 Subject: Introduce custom path and scan providers. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This allows extension modules to define their own methods for scanning a relation, and get the core code to use them. It's unclear as yet how much use this capability will find, but we won't find out if we never commit it.
