> The class SPSDescriptor is kind of hard to understand, and doesn't quite 
> follow the pattern used by other tuple descriptors. Parts of the code don't 
> agree with the documentation (i.e. SPS_TYPE_TRIGGER marked as not implemented)
> This issue tracks work to make the class easier to understand and to modify.
> The critical part that may need to be changed is the use of synchronized 
> (this). The problem is that database locks are obtained within the critical 
> regions, and in some special cases this causes deadlocks. I'm not yet certain 
> this can be fixed at this level (only), but I'll continue investigation.
