Bump PostgreSQL/OpenSSL versions for the binary gem

Lars,

Does this work in your MinGW setup? I can't get PostgreSQL to configure:

    checking for library containing CRYPTO_new_ex_data... no
    configure: error: library 'eay32' or 'crypto' is required for OpenSSL

but I haven't had it working in a long time. Can you test the newest versions out? I'd like to push a pre-release gem, let people test it, then release on the 22nd or so if there aren't any reported major problems.
