Primitives	Integer, Numeric, String, Boolean
Structured	Date/Time, Array, Range, UUID
Document	JSON/JSONB, XML, Key-value (Hstore)
Geometry	Point, Line, Circle, Polygon

The Postgres connector is used to connect and load data from the PostgreSQL database. 

Requirements

Credentials of the database you would like to connect to:

• Host
• Port
• Name of the database
• Username
• Password
• SSH key details (optional, described in more detail below)

If you wish to connect to a database outside of the Meiro environment, you may need a front-end tool like PgAdmin4, Postico, DBeaver or any other front-end (GUI) tool available online. To learn more about these tools, please refer to their respective documentation online. Connecting via a GUI tool is not mandatory, but it may be useful if you want to access the database outside the Meiro environment.

Postgres components work only with CSV tables. Other data formats need to be converted to CSV format by processors.
