From d1ecd539477fe640455dc890216a7c1561e047b4 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Tue, 24 Jan 2017 16:59:18 -0500 Subject: Add a SHOW command to the replication command language. This is useful infrastructure for an upcoming proposed patch to allow the WAL segment size to be changed at initdb time; tools like pg_basebackup need the ability to interrogate the server setting. But it also doesn't seem like a bad thing to have independently of that; it may find other uses in the future. Robert Haas and Beena Emerson. (The original patch here was by Beena, but I rewrote it to such a degree that most of the code being committed here is mine.)
