commit    da6bb58ed9da5ba95b7668e7f4b4c9e2d318a62a
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Fri Jun 08 03:07:03 2012 +0000
First released in: 9.0.9

    Revert "Wake WALSender to reduce data loss at failover for async commit."
    
    This reverts commit 090e8a984cf1a8a3ef7f6db6dc919f843902d80c.
    Since WalSndWakeup does not exist in 9.0, it's clear that this patch
    wasn't even compiled in this branch.  Perhaps some variant of it is
    appropriate in 9.0, but for the moment I'm just going to un-break
    the buildfarm.
