 I assume that the fix works, but I would love to see some tests to
 ensure it is working. Another issue that looks more problematic is the fact
 that, as per the Redmine issue, when an exception is thrown it sends back a
 Successful Query message. If this is the case then this fix doesn't look
 like it is enough to solve the problem.

Re: [pgAdmin4][patch]: RM #3090 pgadmin shows misleading "Query returned successfully" with incorrect SQL

Hi Akshay,

We were not trying to imply that your fix did not solve the problem, we
were trying to understand the root cause of the problem.

1. We were not able to reproduce the problem
We followed your directions in RM, removed your fix but we could not
reproduce the problem. So we could not make sure that the application is in
fact working. This maybe have been because we missed something.
2. The fix does not tackle the big problem
>From what we read on the RM the big problem is "when we throw an exception
the front end is displaying the query successful message". Did you also
understood that from the RM?
We believe this is the real problem behind the RM.
Were you able replicate this behavior? If so we need to address the root of
this.


As an aside sniping bugs is fine in some situations but as a general rule
of thumb is a bad approach and creates a blob of code that no one can
manage. A situation like this look like a very promising candidate for
extraction/refactoring in our point of view. In which situation do you
normally refactor or extract code?

Thanks
Joao

I have mentioned the steps in RM and I have tried it on Ubuntu 16.
Python is complaining the exact line where I have fixed the logic.

   ex_diag_message = u"{0}:  {1}".format(
 self.decode_to_utf8(exception_obj.diag.severity), #
exception_obj.diag.severity is not decoded before my fix.
 self.decode_to_utf8(exception_obj.diag.message_primary)
   )

Yes it works. With the latest code I didn't see Successful Query
message, it is showing "Not connected to the server .", but the stack
trace is same that was mentioned in the RM.
