Why does running a query return 'table_oid' under messages and nothing under Data Output
From pgAdmin 4 project tracker: Temporary solution until next release and tested in my ubuntu 18.04 machine:
Replace these two 2 files:
/usr/share/pgadmin4/web/pgadmin/tools/sqleditor/__init_*_py /usr/share/pgadmin4/web/pgadmin/tools/sqleditor/command.py
Link to files:
__init_*_.py
command.py
Note: The first file's name is __init_*_py, without the *.
