PostgreSQL

The open-source relational database — full SQL support.

Connection fields

Field	Required	Description
`host`	Yes	Hostname or IP address of the Postgres server.
`port`	No	Defaults to 5432.
`user`	Yes	Username to authenticate with.
`password`	No	Not enforced by the connector, but almost every real server requires one — leave it blank only against a server configured to allow passwordless auth.
`dbname`	Yes	Database name to connect to.
`sslmode`	No	One of "disable", "prefer" (default), or "require".

Add data source form for a PostgreSQL connection

Example configuration

{
  "host": "db.internal.example.com",
  "port": 5432,
  "user": "arcodash_reader",
  "password": "••••••••",
  "dbname": "analytics",
  "sslmode": "require"
}

Caveats

arcodash needs network access to reach the host, so a cloud-hosted Postgres instance must accept connections from the internet. arcodash doesn't publish a fixed set of outbound addresses to allowlist — enable SSL/TLS rather than relying on IP filtering.
sslmode "require" only enforces that the connection is encrypted, not that the server certificate is verified against a CA.
