Solaris 10 (64Bit) - Different Behavior on Privileges and Default Privileges Tab Pages of Properties Screen of Database and Schema on pgAdmin III

pgAdmin III (Version 1.12.3)
OS = Solaris 10 (64Bit)

Following are the differences in the behavior on Privileges and
Default Privileges Tab Pages when adding Privileges on the Properties
Sheet of Database and Schema on pgAdmin III.

First Issue
=============
On Privileges Tab Page when a role is added without Privileges (click
on Add/Change button without selecting any check box in Privileges
section) then one row is added with role name in the list and when the
same role is changed by adding the privileges in the Privileges
section then the same row is updated but incase of Default Privileges
Tab (Table, Sequence and Functions sub tabs) when the same above steps
are followed then two rows are added, one with role name and second
with role name and the assigned privileges. One Row must be added on
Default Privileges Tab same as on Privileges Tab.

Second Issue
==============
After performing the steps in First Issue when the row is selected and
remove button is pressed on Privileges Tab then the row is deleted
from the list and now if Add/Change button is clicked (without
selecting any check box in Privileges section) then another row is
added with selected role. But on Default Privileges Tab (Table,
Sequence and Functions sub tabs) afrer deleteing the added rows if
Add/Change button is pressed (without selecting any check box in
Privileges section) then no new row is added with selected role. The
row should be added with select role on Default Privileges Tab same as
on Privileges Tab.
