ALTER INDEX xxxx MAINTENANCE IS DISABLED would be helpful, so that
you don't have to be dragging around (possibly changing) SQL around
"everywhere".

So, an example would be from an evening load job would be:
ALTER INDEX foobar_idx MAINTENANCE IS DISABLED;
COPY foo FROM 'blarg';
REINDEX INDEX foobar_idx;

So if the DBA decides that foobar_idx needs different fields, you
don't have to edit the evening load job when the index changes.
