#ifndef BOOTSTRAP_H
#define BOOTSTRAP_H
Cleanup of code for creating index entries. Functional indexes with pass-by-ref data types --- eg, an index on lower(textfield) --- no longer leak memory during index creation or update. Clean up a lot of redundant code ... did you know that copy, vacuum, truncate, reindex, extend index, and bootstrap each basically duplicated the main executor's logic for extracting information about an index and preparing index entries? Functional indexes should be a little faster now too, due to removal of repeated function lookups. CREATE INDEX 'opt_type' clause is deimplemented by these changes, but I haven't removed it from the parser yet (need to merge with Thomas' latest change set first).

Simplify the bootstrap (BKI) code by getting rid of a useless table of all the strings seen during the bootstrap run. There might have been some actual point to doing that, many years ago, but as far as I can see the only value now is to conserve a bit of memory. Even if we cared about wasting a megabyte or so during the initdb run, it'd be far more effective to arrange to release memory at the end of each BKI command, instead of intentionally hanging onto strings that might never be used again. Not maintaining the table probably makes it faster too; but the main point of this patch is to get rid of a couple hundred lines of unnecessary and rather crufty code.

Support toasting of shared system relations, and provide toast tables for pg_database, pg_shadow, pg_group, all of which now have potentially-long fields. Along the way, get rid of SharedSystemRelationNames list: shared rels are now identified in their include/pg_catalog/*.h files by a BKI_SHARED_RELATION macro, while indexes and toast rels inherit sharedness automatically from their parent table. Fix some bugs with failure to detoast pg_group.grolist during ALTER GROUP.

Get rid of IndexIsUniqueNoCache() kluge by the simple expedient of passing the index-is-unique flag to index build routines (duh! ... why wasn't it done this way to begin with?). Aside from eliminating an eyesore, this should save a few milliseconds in btree index creation because a full scan of pg_index is not needed any more.

Unify calling conventions for postgres/postmaster sub-main functions There was a wild mix of calling conventions: Some were declared to return void and didn't return, some returned an int exit code, some claimed to return an exit code, which the callers checked, but actually never returned, and so on. Now all of these functions are declared to return void and decorated with attribute noreturn and don't return. That's easiest, and most code already worked that way.

extern void InsertOneTuple(Oid objectid);
Make OIDs optional, per discussions in pghackers. WITH OIDS is still the default, but OIDS are removed from many system catalogs that don't need them. Some interesting side effects: TOAST pointers are 20 bytes not 32 now; pg_description has a three-column key instead of one. Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey has some usefulness; pg_dump dumps comments on indexes, rules, and triggers in a valid order. initdb forced.

Fix off-by-one loop count in MapArrayTypeName, and get rid of static array. MapArrayTypeName would copy up to NAMEDATALEN-1 bytes of the base type name, which of course is wrong: after prepending '_' there is only room for NAMEDATALEN-2 bytes. Aside from being the wrong result, this case would lead to overrunning the statically allocated work buffer. This would be a security bug if the function were ever used outside bootstrap mode, but it isn't, at least not in any currently supported branches. Aside from fixing the off-by-one loop logic, this patch gets rid of the static work buffer by having MapArrayTypeName pstrdup its result; the sole caller was already doing that, so this just requires moving the pstrdup call. This saves a few bytes but mainly it makes the API a lot cleaner. Back-patch on the off chance that there is some third-party code using MapArrayTypeName with less-secure input. Pushing pstrdup into the function should not cause any serious problems for such hypothetical code; at worst there might be a short term memory leak. Per Coverity scanning.
