Yes that's configured on the master

So the segments would pile up there not on the standby. You do not say what OS you are using, but if it is a Unixen variation, then run:

du -h

on the master and standby directories to see where the capacity is being used.

        The db's both reside on a 250GB directorys and on the Master i'm
        using
        60% of capacity which seems expected
        On the secondary i am using 88% of the disks capacity. I assume
        this is
        something to do with the WAL segments ? which is currently
        wal_keep_segments = 500


    That is for the server sending the segments, so I would assume you
    are getting this number from the master not the standby?


        If this is the issue how do i go about tuning this to what is
        required ?

        If i make the segments to small then a restore may end up with an un
        synchronised database right ?

        thanks.
