#ifndef PG_ATTRDEF_H
#define PG_ATTRDEF_H
Reduce the need for frontend programs to include "postgres.h" by refactoring inclusions in src/include/catalog/*.h files. The main idea here is to push function declarations for src/backend/catalog/*.c files into separate headers, rather than sticking them into the corresponding catalog definition file as has been done in the past. This commit only carries out that idea fully for pg_proc, pg_type and pg_conversion, but that's enough for the moment --- if pg_list.h ever becomes unsafe for frontend code to include, we'll need to work a bit more.

First phase of project to use fixed OIDs for all system catalogs and indexes. Extend the macros in include/catalog/*.h to carry the info about hand-assigned OIDs, and adjust the genbki script and bootstrap code to make the relations actually get those OIDs. Remove the small number of RelOid_pg_foo macros that we had in favor of a complete set named like the catname.h and indexing.h macros. Next phase will get rid of internal use of names for looking up catalogs and indexes; but this completes the changes forcing an initdb, so it looks like a good place to commit. Along the way, I made the shared relations (pg_database etc) not be 'bootstrap' relations any more, so as to reduce the number of hardwired entries and simplify changing those relations in future. I'm not sure whether they ever really needed to be handled as bootstrap relations, but it seems to work fine to not do so now.
