Hi Tony,
according to this Stackoverflow post
<https://stackoverflow.com/questions/49919149/unable-to-connect-to-postgresql-with-pgadmin4-readonly-attribute-error>
, the error seems to be caused by a too old psycopg2 library. Perhaps you
can upgrade to v2.7, or just comment out line 313 of
/usr/share/pgadmin4/web/pgadmin/utils/driver/psycopg2/connection.py as some
kind of "dirty hack", but be aware that I don't know the "deeper
consequences" of doing so.
Hope this helps.
Cheers,
Frank.
