Hi all,

I would like to know what this message means, maybe a bug??

psql> select * from capi;
ERROR:  XLogFlush: request 0/6173A2D8 is not satisfied --- flushed only to 0/616E519C

This message is showed by psql in a random mode. 

Thanks for any help,

Jose

This suggests a corrupted LSN on some disk page, but without any context
I can't say more than that.

Is the "request" value always the same?  If so, it's probably just one
page that's messed up --- you could figure out which one with a
debugger.  (XLogFlush unfortunately doesn't know why it's being called,
so it can't print any more info.)
