Hi Dave,
Further to our discussion on this issue, it seems the problem is with the length of the text in the grid. Thanks for your guidance.
In windows 7, if the length of a string in the grid exceeds "4679", then it's not able to render the values properly.
SELECT substring(geom::text from 1 FOR 4679) FROM plz;
If i execute the above statement, then it's showing all the 16 values. But this is not the case in the CentOS.
Kindly let me know how to proceed on this issue.
Thanks in advance.
