Attached patch uses "safe" isolation level for remote transactions.
After this change, pgsql_fdw uses levels below:

      local       |     remote
------------------+-----------------
 SERIALIZABLE     | SERIALIZABLE
 REPEATABLE READ  | REPEATABLE READ
 READ COMMITTED   | REPEATABLE READ
 READ UNCOMMITTED | REPEATABLE READ

Please review document of pgsql_fdw too.

In addition, I've removed #ifdef from options.c, so that we can specify
libpq options about SSL and Kerberos even if such feature has not been
configured on the environment where pgsql_fdw was built.  This change
also avoids regression test failure on environment where any of
--with-openssl or --with-krb5 was specified for configure script.
