Re: SPITupleTable members missing in docs

Patch applies cleanly, doc build ok.

To take into account Tom's comment, I'd suggest a middle ground by 
commenting a public and private part explicitely in the struct, something 
like:

   typedef struct {
     /* PUBLIC members to be used by callers ... */
     ...
     ...
     /* PRIVATE members, not intended for external usage ... */
     ...
   } ... ;

Another option would be to use some python-like naming convention on such 
members, eg with a leading underline character.

Even if it is redundant with the paragraph below, it would make things 
visually clear as well.

Note: I'm probaly not a member of the pgdoc list, so the delivery may fail 
there.
