Add missing check for wal_debug GUC.

anarazel · anarazel · commit 90231cd5188c · 2015-06-21T18:37:09.000+02:00
9a20a9b added a new elog(), enabled when WAL_DEBUG is defined. The other WAL_DEBUG dependant messages check for the wal_debug GUC, but this one did not. While at it replace 'upto' with 'up to'. Discussion: 20150610110253.GF3832@alap3.anarazel.de Backpatch to 9.4, the first release containing 9a20a9b.
