First phase of plan-invalidation project: create a plan cache management module and teach PREPARE and protocol-level prepared statements to use it. In service of this, rearrange utility-statement processing so that parse analysis does not assume table schemas can't change before execution for utility statements (necessary because we don't attempt to re-acquire locks for utility statements when reusing a stored plan). This requires some refactoring of the ProcessUtility API, but it ends up cleaner anyway, for instance we can get rid of the QueryContext global. Still to do: fix up SPI and related code to use the plan cache; I'm tempted to try to make SQL functions use it too. Also, there are at least some aspects of system state that we want to ensure remain the same during a replan as in the original processing; search_path certainly ought to behave that way for instance, and perhaps there are others.

#include "nodes/parsenodes.h"
#include "utils/rel.h"
Another pgindent run. Fixes enum indenting, and improves #endif spacing. Also adds space for one-line comments.

Report index name on CLUSTER failure. Also, suggest ALTER TABLE WITHOUT CLUSTER for cluster failure of a single table in a full db cluster.

extern void check_index_is_clusterable(Relation OldHeap, Oid indexOid,
Standard pgindent run for 8.1.

bool recheck);
Get rid of cluster.c's apparatus for rebuilding a relation's indexes in favor of using the REINDEX TABLE apparatus, which does the same thing simpler and faster. Also, make TRUNCATE not use cluster.c at all, but just assign a new relfilenode and REINDEX. This partially addresses Hartmut Raschick's complaint from last December that 7.4's TRUNCATE is an order of magnitude slower than prior releases. By getting rid of a lot of unnecessary catalog updates, these changes buy back about a factor of two (on my system). The remaining overhead seems associated with creating and deleting storage files, which we may not be able to do much about without abandoning transaction safety for TRUNCATE.
