If you get a chance, it still may be worth giving 0.60 a try and
seeing if helps at all.
I don't remember all of the changes, but back around 0.58 we changed how
pg_info updates work which really improved small IO performance but did
provide a bit of a boost for large IOs too. Not sure if it will make as
much of a different with EXT4, but it may be worth a shot if you haven't
deployed a bunch of data yet.
I could not see any information about major changes in 0.60 that may
improve performances, do you have any pointer for this?
