Agreed. Seems we have several issues:
filename contentstablespace implementationtablespace directory layouttablespace commands and syntax
Filename syntax seems to have resolved to
tablespace/tablename_oid_version or something like that. I think a
clean solution to keep symlink names in sync with rename is to use hard
links during rename, and during vacuum, if the link count is greater
than one, we can scan the directory and remove old files matching the
oid.
I hope we can implement tablespaces using symlinks that can be dump, but
the symlink location does not have to be stored in the database.
Seems we are going to use Extent-2/Extent-3 to store extents under each
tablespace.
It also seems we will be using the Oracle tablespace syntax where
appropriate.
