I don't undestand the ODS structure, but isn't possible something like this?

Insert the new records in "unlinked" pages without storing in the
indexes (if they exist). These pages are not visible to selects.
After the records are inserted, the pages is linked to be visible by
sequential scan, and the indexes entries are added.
