They don't all have to be non-WAL, first off; it could be optional per
index. Second, non-WAL would provide a benefit in the case the OP
mentioned, and the only time it would be a detriment is in the event of
a fault. Reindexing of non-WAL indexes could be automatic during recovery.
Non-WAL indexing is an option I would almost certainly take advantage of
if it existed.
