[BUG] Get rid of pseudo-clobbering error messaging

Describe the bug

Rubbish Error message pseudo-clobbering. Some of the real error generally persists (as per screen capture). Only a meaningful error message should be displayed, no rubbish boilerplate.

To Reproduce

See screen capture.

This one is easy to reproduce using a select operation; just misspell the select keyword, eg: slct sizeGb from google.compute.disks where project = 'stackql-demo' and zone = 'australia-southeast1-a';.

Expected behavior
A clear and concise description of what you expected to happen.

Additional context
Add any other context about the problem here.

Riproduci il problema con la query scritta erroneamente slct su google.compute.disks, quindi traccia il modo in cui l’operazione di selezione formatta gli errori del parser. Il lavoro è completato quando l’output contiene solo un messaggio di errore chiaro, conciso e significativo, senza il boilerplate irrilevante mostrato nello screenshot.
