* The patch changes HeapTupleGetDatum from a simple inline macro into a function call. This means that third-party extensions will not get protection against creation of toast-pointer-containing composite Datums until they recompile.
One consequence of that is that an extension compiled with headers from new minor version won't work with binaries from an older minor version. Packagers beware.
