Spark SQL data source can read data from other databases using JDBC.JDBC connection properties such as user and password are normally provided as connection properties for logging into the data sources.

In the example below I am using MySQL, so will need to have the Postgres drivers in place

Sample Program

import org.apache.spark.sql.SQLContext
val sqlcontext = new org.apache.spark.sql.SQLContext(sc)
val dataframe_mysql = sqlcontext.read.format("jdbc").option("url", "jdbc:mysql://mbarara.com:3306/test").option("driver", "com.mysql.jdbc.Driver").option("dbtable", "emp").option("user", "root").option("password", "welcome1").load()
dataframe_mysql.show()

Hope that helps
