Update datasource script corrupted hyper file with SQLSTATE:08001 error

[pakosel]

Bug description
I've used https://github.com/tableau/server-client-python/blob/master/samples/update_datasource_data.py script to delete some rows from a hyper file. I was testing condition arguments and deleting 1k-10k rows worked fine. Then I tried to delete random 20k rows from this hyper and it failed, connection was closed by the server with the following message:

INFO:tableau.endpoint.jobs:Job eb23d972-5a9a-41ef-be67-2a38c1136e0a Completed: Finish Code: 1 - Notes:['com.tableausoftware.nativeapi.exceptions.ConnectivityException: [SQLSTATE:08006] The Hyper server closed the connection unexpectedly: pqsecure_raw_read\r\nThe server process may have been shut down or terminated before or while processing the request.\nUnable to connect to the Tableau Data Extract server "".

After this, the hyper file becomes unusable - cannot trigger incremental or full refresh - each job finishes with the following message:

An internal error occurred. Contact your administrator. com.tableausoftware.server.status.reporting.TableauRuntimeException: System error: TableauException: [SQLSTATE:08001] Could not connect to the Hyper server: Connection refused (0x0000274D/10061) Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 8711? An internal error occurred. Contact your administrator.
