title: How to solve ProviderManifestToken="8.3.7" and Npgsql ProviderManifestToken="8.1.3" conflict?
body: <p>I'm trying to connect to my PostgreSQL database using Entity Framework. Unfortunately after generating a model using EdmGen (or EdmGen2) in my SSDL file ProviderManifestToken is set to 8.3.7 when in the current version of Npgsql (2.0.9) it is set to 8.1.3. This gives me fallowing exception when trying to use my entity model:</p>
  
  <blockquote>
    <p>System.Data.MetadataException: Schema
    specified is not valid. Errors: 
    Npgsql.NpgsqlSchema.ssdl(2,52) : error
    0169: All SSDL artifacts must target
    the same provider. The
    ProviderManifestToken '8.1.3' is
    different from '8.3.7' that was
    encountered earlier.</p>
  </blockquote>
  
  <p>Any ideas how to fix it or generate a model with ProviderManifestToken eq 8.1.3?</p>
  
  <p>Please don't suggest commercial database connectors my budget won't allow it :P</p>
