Detection of postgres URI connection string - Maybe undesired behavior

[arielril]

Hey guys, I am using Trufflehog in a test folder where I have different Kubernetes deployment files, one of those files has a postgres URI connection string pointing to a local database.

Trufflehog fails to find this URI connection string because the connection string doesn't have the password set.

Question: Is this the desired behavior to not detect URI connection strings without the password set or it should detect?

This issue happens because of a verification if the URI connection has the password set or not. This is the code that stops the detection of the URI connection:

// https://github.com/trufflesecurity/trufflehog/blob/c05bb4d7ea587a541e39bae217ab2049a7de1628/pkg/detectors/postgres/postgres.go#L80
func (s Scanner) FromData(ctx context.Context, verify bool, data []byte) ([]detectors.Result, error) {
	var results []detectors.Result
	candidateParamSets := findUriMatches(data)

	for _, params := range candidateParamSets {
		if common.IsDone(ctx) {
			break
		}
		user, ok := params[pgUser]
		if !ok {
			continue
		}

		password, ok := params[pgPassword]
		if !ok { // this condition stops the detection
			continue
		}
....

If this is not the intentional behavior I'm happy to send a PR with the expected execution.
