PostgreSQL Metrics

# Read metrics from one or many postgresql servers
[[inputs.postgresql]]
  ## Specify address via a url matching:
  ##   postgres://[pqgotest[:password]]@localhost[/dbname]?sslmode=[disable|verify-ca|verify-full]&statement_timeout=...
  ## or a simple string:
  ##   host=localhost user=pqgotest password=... sslmode=... dbname=app_production
  ## Users can pass the path to the socket as the host value to use a socket
  ## connection (e.g. `/var/run/postgresql`).
  ##
  ## All connection parameters are optional.
  ##
  ## Without the dbname parameter, the driver will default to a database
  ## with the same name as the user. This dbname is just for instantiating a
  ## connection with the server and doesn't restrict the databases we are trying
  ## to grab metrics for.
  ##
  address = "host=localhost user=postgres sslmode=disable"
 
  ## A custom name for the database that will be used as the "server" tag in the
  ## measurement output. If not specified, a default one generated from
  ## the connection address is used.
  # outputaddress = "db01"
 
  ## connection configuration.
  ## maxlifetime - specify the maximum lifetime of a connection.
  ## default is forever (0s)
  ##
  ## Note that this does not interrupt queries, the lifetime will not be enforced
  ## whilst a query is running
  # max_lifetime = "0s"
 
  ## A  list of databases to explicitly ignore.  If not specified, metrics for all
  ## databases are gathered.  Do NOT use with the 'databases' option.
  # ignored_databases = ["postgres", "template0", "template1"]
 
  ## A list of databases to pull metrics about. If not specified, metrics for all
  ## databases are gathered.  Do NOT use with the 'ignored_databases' option.
  # databases = ["app_production", "testing"]
 
  ## Whether to use prepared statements when connecting to the database.
  ## This should be set to false when connecting through a PgBouncer instance
  ## with pool_mode set to transaction.
