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).
