for indexes. it seems pageinspect only deals with btree indexes and i
neglected to put a similar limitation on this function... now, because
the free space is calculated using PageGetFreeSpace() for indexes it
should be doing the right thing for all kind of indexes, i only put
the function there because i was trying to avoid to create a new file.
But if the function is right for all kind of indexes that's maybe
enough to create a new file and rename the helper function so is
obvious that it can manage all kind of indexes
for toast tables. a simple test here seems to show that is as easy as
to add toast tables in the supported objects and treat them as normal
pages...
or there is something i'm missing?
