This path configures the connection string used to connect to PostgreSQL.

The value of the string can be a URL, or a PG style string in the

format of "user=foo host=bar" etc.
|
|

|
The URL looks like:
|

"postgresql://user:pass@host:port/dbname"
|

|
|
When configuring the connection string, the backend will verify its validity.
