From 401aad67045b2d467571b54abe229fdd115a228c Mon Sep 17 00:00:00 2001 From: Michael Paquier Date: Thu, 30 Apr 2020 13:39:10 +0900 Subject: [PATCH] Rename connection parameters to control min/max SSL protocol version in libpq The libpq parameters ssl{max|min}protocolversion are renamed to use underscores, to become ssl_{max|min}_protocol_version. The related environment variables still use the names introduced in commit ff8ca5f that added the feature. Per complaint from Peter Eisentraut (this was also mentioned by me in the original patch review but the issue got discarded).
