<p dir="auto">Hi Github Fam,</p>
<p dir="auto">I am now successfully able to configure new Postgres database and able to connect to SuperSet via it but I am still not able to use upload CSV option, it gives me error that "ERROR: Failed to fetch schemas allowed for csv upload in this database! Please contact your Superset Admin!".  I have already selected "allowed CSV upload" option from EXTRA tab. Please suggest.</p>
<p dir="auto">Alternate solution - I created dummy data in database and then pulled it via SQL in Superset.</p>
<p dir="auto">Warm Regards,</p>
