connect string

[skad0Osh]

Incase we have multiple databases per PGSID, what database should we use for the connect string?
If we use default database postgres, data for database specific stats like pg_stat_user_tables does not include data from all the databases. Should we run one exporter per database?

One exporter per DB was the original design. There is now multi-DB support, and some support for master->extra databases.

queries.yml is an area of the code I've only ever had very limited use for personally but got superuseful to everyone else.
