Hello,


The attached trivial patch fixes the initialization of the fake unlogged LSN.  Currently, BootstrapXLOG() in initdb sets the initial fake unlogged LSN to FirstNormalUnloggedLSN (=1000), but the recovery and pg_resetwal sets it to 1.  The patch modifies the latter two cases to match initdb.

I don't know if this do actual harm, because the description of FirstNormalUnloggedLSN doesn't give me any idea.
