How to ignore system indexes

Hi all,

I'm trying to implement REINDEX command.
Because the command is to repair system indexes,we
coundn't rely on system indexes when we call the
command.

I added locally an option of standalone postgres to ignore
system indexes and am add/changing ignore_system_
indexes stuff.

There are fairly many places using system indexes.
Probably I would be able to change them.
But is it preferable or possible to force other developers
to take ignore_system_indexes mode into account ?
Is it better to limit changes required for REINDEX
command ?

Comments ? Better ideas ?

Regards.
