Hi

Unfortunately this has introduced a regression:

- Start pgAdmin from the command line or PyCharms.

- Connect to a server, open a query tool and run a query (SELECT 1 will do).

- Stop and restart the pgAdmin server.

- Execute the query again in the client.

The error "'Connection' object has no attribute 'python_encoding'" is returned in the messages tab and the following exception is given on the pgAdmin server:

2019-03-01 16:07:26,293: ERROR pgadmin: 'Connection' object has no attribute 'python_encoding'

I'm guessing there's a codepath in which connection objects are created without the python_encoding attribute.

Hi,

Please find the attached patch to fix the encoding related issues.

#3992 - View data causes errors with DB encoding EUC_JIS_2004

#3982 - Encoding Problem with PGAdmin 4.2

#3911 - Data output does not display Arabic in WIN1256 encoding database

- The CSV download for the same encoding has also been fixed.

I have tested the patch on Python 2.7, 3.5, 3.6 and 3.7.

You've added a couple of new encodings, but it seems to me that we should just add everything that PostgreSQL supports. For example, we now have win1256, but what about 866, 874, 1250, 1251 etc?

The full list is at https://www.postgresql.org/docs/11/multibyte.html

Any reason not to do that?

I thought to fix the reported bugs first and after that, I was about to add a new ticket to add the remaining supported encodings.

But as per you, I will add the remaining encodings along with these fixes.
