Martin Tile Server Documentation

PostgreSQL Connection String

Martin supports many of the PostgreSQL connection string settings such as host, port, user, password, dbname, sslmode, connect_timeout, keepalives, keepalives_idle, etc. See the PostgreSQL docs for more details.

PostgreSQL SSL Connections

Martin supports PostgreSQL sslmode including disable, prefer, require, verify-ca and verify-full modes as described in the PostgreSQL docs. Certificates can be provided in the configuration file, or can be set using the same env vars as used for psql. When set as env vars, they apply to all PostgreSQL connections. See environment vars section for more details.

By default, sslmode is set to prefer which means that SSL is used if the server supports it, but the connection is not aborted if the server does not support it. This is the default behavior of psql and is the most compatible option. Use the sslmode param to set a different sslmode, e.g. postgresql://user:password@host/db?sslmode=require.
