Well, if per the subject line, you're expecting the POST encoder to
deflate the SAML message: That's incorrect.  In the SAML 2 POST
binding, there is no deflation like in the Redirect-DEFLATE binding. 
The serialized XML is simply base64-encoded and placed into the form. 
SAML Bindings, section 3.5.4:
