htup and bufpage API clean up
Attached patch contains code cleanup in htup.h nad bufpage.[ch]. This patch is part of pg upgrade project. Idea of this patch is to remove any direct access to PageHeader and HeapTupleHeader. I already sent more complex patch including mutli page version control last commitfest. This patch does not contain multi page version control. I will send it separately. Main changes in bufpage: ------------------------ - Remove PageGetItem/PageGetItemId. It has been replaced by PageGetHeapTuple and PageGetIndexTuple - Most macros are converted to functions. It will be necessary for following patch. Main changes in htup: --------------------- - htup.c is created - Most macros HeapTupleHeader* are removed - Add complete set of HeapTuple* functions - Macros for "DatumTupleHeader" still remain, because they are use in PL Other changes are related to the new API. Several patches in a patch queue uses old API. It will require consolidation. Zdenek -- Zdenek Kotala Sun Microsystems Prague, Czech Republic http://sun.com/postgresql
