Passwords with blanks are not working

[ebini]

Trying to use a password (sentence with multiple blanks)

using wrouesnel/postgres_exporter:v0.8.0

Tried is with envirnoment variable, passwordfile or as datasource name, also with %20 instead of blanks. (changed username and replaced words) This try was with DATA_SOURCE_NAME replaced blanks with %20

malformed dsn \"dbname=changed host=changed.com password=foo\\\\ test\\\\ foo\\\\ test\\\\ foo\\\\ hello port=5431 user=abcd123\"" source="postgres_exporter.go:1474"

Thanks
