title: View a list of all schema in a PostgreSQL database in r?
body: <p>I'm connecting and querying a PostgreSQL database through the <code>dplyr</code> package in R. I know I can list all the tables in the database using <code>dbListTables(con)</code>.
  But, my tables are organized into different schema. What is the easiest way I can view all of the schema that are present in my database using R?</p>
