Thanks for the really good hints on TINs with PostGIS.
yes, Oracle have implemented a TIN type for their 11g release. It's called SDO_TIN, which allows creation and querying of TINs. It works by having two tables. One that has a column with the SDO_TIN type which contains meta data. The points of the TIN are divided into subsets and stored as multiple rows in the points BLOB column. So there is a base table (the one with the SDO_TIN) and a block table. The triangle information is also stored as a BLOB column.
