Configure the connection string to talk to PostgreSQL.

`

const pathConfigConnectionHelpDesc = `
|
|
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.
