Subject: xlogfuncs.c: Use GetCurrentTimeLineID() instead of ThisTimeLineID.
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=cb412b73629e798e92df40f92d396f04aa3234e3;p=users%2Frhaas%2Fpostgres.git

xlogfuncs.c: Use GetCurrentTimeLineID() instead of ThisTimeLineID.

The value can't be changing concurrently, because these functions
can't be run during recovery. So there's no problem.
