Please find updated patch. Now placeholder string for bytea and bytea[] data will only appear in datagrid (view all/1000/500 rows). If user executes query using Query tool then placeholder won't appear (similar to pgAdminIII behaviour)
I'm getting the following error when testing this:
I ran all feature test cases 5-6 times and each time they ran successfully.
May be this is occasional failure which we get after running test cases for many times.
Please let me know if you are getting this failure consistently at your end.
I ran it twice and it failed twice. I can't keep running tests over and over again as they take quite a while to run and I can't use my machine for anything else at the same time as occasionally the test browser will grab focus.
