It seems strange to me that nobody else reported this behavior, maybe a

It just me or what ?. :-).

Today I compiled revision 4455, with an updated postgresql 8.1 beta 2
and still can't modify any table due to "ADD before DROP" issue.

It seems to happen only in table properties dialog. I can add or modify
any table object using ad-hoc property dialogs.

To reproduce it, open a table property dialog and look to SQL tab. It
should say "-- nothing to change" but in my case shows constraints's add
code and corresponding constraints's drop code.
