Fix that npm start "db.psql_k8s dm-ovh" mangles the display of some special characters (eg. line/column chars for table displays) in certain cases (eg. long outputs)

[Venryx]

Replication:

1. Run: npm start "db.psql_k8s dm-ovh"
2. Execute: SELECT set_config('app.current_user_id', 'D1Y6EhKuTFCE--91TusIQA', false);
3. Execute: SELECT * FROM global_search('nuclear power', 100);

Note: Only appears to happen on M-A's machine atm. (not on my Windows desktop anyway)
