  # specify address via a url matching:
  # postgres://[pqgotest[:password]]@host:port[/dbname]?sslmode=...&statement_timeout=...
  # or a simple string:
  #   host=localhost port=5432 user=pqgotest password=... sslmode=... dbname=app_production
  #
  # 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"

  ## 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.

  # Define the toml config where the sql queries are stored
  # The script option can be used to specify the .sql file path.
  # If script and sqlquery options specified at same time, sqlquery will be used
  #
  # the measurement field defines measurement name for metrics produced
  # by the query. Default is "postgresql".
  #
  # the tagvalue field is used to define custom tags (separated by comas).
  # the query is expected to return columns which match the names of the
  # defined tags. The values in these columns must be of a string-type,
  # a number-type or a blob-type.
  #
  # The timestamp field is used to override the data points timestamp value. By
  # default, all rows inserted with current time. By setting a timestamp column,
  # the row will be inserted with that column's value.
  #
  # The min_version field specifies minimal database version this query
  # will run on.
  #
  # The max_version field when set specifies maximal database version
  # this query will NOT run on.
  #
  # Database version in `minversion` and `maxversion` is represented as
  # a single integer without last component, for example:
  # 9.6.2 -> 906
  # 15.2 -> 1500
  #

  #   max_version int
  #   withdbname boolean
  #   tagvalue string (coma separated)
