Hi,
when server message is not english (my server is korean),
pgadmin4 make a error bellow.
File
"/usr/lib/python2.7/site-packages/pgadmin4-web/pgadmin/utils/driver/psycopg2/__init__.py",
line 1612, in _formatted_exception_msg
self.decode_to_utf8(exception_obj.diag.message_primary)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xec in position 0:
ordinal not in range(128)
This pgadmin4 is pgadmin4-v2-2.0-1.rhel7.x86_64.rpm package on CentOS7.
It may be a problem utf8 encoding string processing of python 2.7.
I sugesst , if server message is non english, decoding to utf8 is skiped.
