[PATCH] postgresql.conf.sample->postgresql.conf.sample.in

[i . taranov]

A patch for converting postgresql.conf.sample to 
postgresql.conf.sample.in . This feature allows you to manage the 
contents of postgresql.conf.sample at the configure phase.

Usage example:
    ./configure --enable-foo


configure.in:

    foo_params=$(cat <<-END
      foo_param1 = on
      foo_param2 = 16
    END
    )
    AC_SUBST(foo_params)


postgresql.conf.sample.in:

    @foo_params@


postgresql.conf.sample:

    foo_param1 = on
    foo_param2 = 16
