Hi,
From the pg_xlog folder, I found some files with interesting time stamps: older file names with newer timestamps, can you please advise why?
Set 1: How come 0000000400000F490000008D is 10 minutes newer than 0000000400000F490000008E?

Set 2: why files, 0000000400000F48000000FD, 0000000400000F48000000FE and 0000000400000F4900000000, are not reused?
