Upcoming changes introduce further types of tuple table slots, in preparation of making table storage pluggable. New storage methods will have different representation of tuples, therefore the slot accessor should refer explicitly to heap tuples. Instead of just renaming the functions, split it into one function that accepts heap tuples not residing in buffers, and one accepting ones in buffers. Previously one function was used for both, but that was a bit awkward already, and splitting will allow us to represent slot types for tuples in buffers and normal memory separately. This is split out from the patch introducing abstract slots, as this largely consists out of mechanical changes.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
