+## Postgres Connection

+```{hint}
+Using `trino+http` as connection protocol disables SSL for the connection. Example: `trino+http://host:port/catalog
+Notice that basic auth requires SSL for Trino.
+```
+
+```py
+import connectorx as cx
+conn = 'trino+https://username:password@server:port/catalog'     # connection token
+query = "SELECT * FROM table"                                    # query string
+cx.read_sql(conn, query)                                         # read data from Trino
