Re: Streaming replication on 9.1-beta2 after pg_restore is very slow

Looking back, I notice that you built with gcc 4.6.0.  At least on Red
Hat machines, that gcc has a rather nasty optimization bug that breaks
WAL replay, with symptoms that seem to match what you have here ---
namely, the replay process quits and has to be restarted every few pages.
I'm betting Debian hasn't fixed that bug yet either and so you need this
post-beta2 patch:
