Hello,
As of today, if you want to add a PostgreSQL in database connection, you may feel embarrased :
However, the help states that PostgreSQL is supported by in-database.

Whaaaaaaaaat?
oh, I forgot to mention : with a little luck, you can find tis help page : https://help.alteryx.com/current/DataSources/PostgreSQL.htm
Yep, you have to configure a "greenplum" connection if you want to use a PSQL.
i think this is not user-friendly and can lead to mistake, errors, frustration and even lack of sales for Alteryx :

Also, Greeenplum and PSQL will have separate features so I think having two separate entries in the menu is pertinent.

Simon
