I have made most system indexes unique.
I have added indexes to match all system caches.
I have renamed some cache names to be clearer.
I have re-ordered the cache entries to be alphabetical.
I have renamed the inheritance *rel columns to be *relid.
I have added a large comment to syscache.c listing steps needed to
install a new system index.
I saw no speed improvement from my changes, but I can imagine cases
where this would be a speedup.
The only thing missing is that I can't seem to get pg_shadow to use an
index from the cache. When I try it, initdb runs really slow, and the
resulting installation is unusable. Any ideas anyone? You can see my
commented-out code in indexing.c and syscache.c. My guess is that the
strange way we issue pg_exec_query_dest() calls is the cause. I have no
call to CatalogIndexInsert() for the pg_shadow because of this. Anyone
want to rewrite user.c to use heap_insert() instead.
initdb required.
