Subject: Do not call pager_open_journal() from within PagerBegin() if the connection is in... 
X-Git-Tag: version-3.7.2~213

Do not call pager_open_journal() from within PagerBegin() if the connection is in exclusive-access mode. It will be called from within PagerWrite() just as it is for non-exclusive mode anyway.
