Remove trace_recovery_messages
This GUC was intended as a debugging help in the 9.0 area when hotstandby and streaming replication were being developped, able to offermore information at LOG level rather than DEBUGn. There are more toolsavailable these days that are able to offer rather equivalentinformation, like pg_waldump introduced in 9.3. It is not obvious howthis facility is useful these days, so let's remove it.Author: Bharath RupireddyDiscussion:https://postgr.es/m/ZXEXEAUVFrvpquSd@paquier.xyz
