Other commands I've ran, tried directly from DB, from file etc...

51  pgloader db.load
52  pgloader Database.db postgresql:///IW4MAdminTest
53  pgloader db.sqlite postgresql:///IW4MAdminTest
54  pgloader --type sqlite db.sqlite postgresql:///IW4MAdminTest

If I try load from Database directly I get Code READONLY: attempt to write a readonly database.

From the db.load file

LOAD DATABASE
       FROM sqlite:///opt/db.sqlite
       INTO postgresql:///IW4MAdminTest;

There's no winning...
