Simon,
Here's some ideas for areas where I think there is a significant
difference between Oracle and PostGIS
- Oracle's tolerance-based precision model VS ??? in PostGIS
- 3D support
- Geodetic data support
- robustness (may be hard to provide examples, but I have seeen some
fairly simple functions (eg buffer) completely kill the Oracle
instance. PostGIS no doubt has its own failure modes)
- external tools for loading and viewing spatial data

Folks,
I am giving a talk at FOSS4G in Sydney next week. That talk's title
and abstract are:
==================================================================
Title: PostGIS and Oracle Spatial
Abstract:
Oracle Spatial and PostGIS are two of the most mature implementations
of a spatial type system for their relevant host databases.
With Postgres increasing in strength, and offshoot EnterpriseDB aiming
to convert businesses running Oracle to EnterpriseDB/Postgres, the
question of the relative merits of each of the spatial implementations
arises.
This talk will attempt to provide the audience with an understanding
of the relative strengths and weaknesses of the two implementations so
that they can feel they have some useful information which might aid
decision making for new installations or conversions.
==================================================================
While I already have quite a bit of material I thought I would ask the
PostGIS community for suggestions as to what they would like covered
if they were attending FOSS4G. Nothing worse than attending a
presentation and, at the end, saying to youself that it was not what
you expected and that nothing much was of use.
So, what sorts of things do you think should be covered?
regards
SImon
