Just so everyone is aware, one of the reasons there aren't as many answers to 
the questions being asked on this list is that Dave Blasby is on holidays in 
Guatemala, and Paul Ramsey is visiting Amsterdam and Paris... They are 
certainly the people who would best answer a question like this, in addition to 
usually offering some help with your general PostGIS problems.

I am not very familiar with Oracle spatial, could you tell me exactly what the 
parameters and output of the this "nearest" function are? I guess the simplest 
answer to your question would be: "Is the 'nearest' operator in the OGC SFSQL 
spec?" - if it is, then it will almost certainly be implemented this summer, 
because the primary goal right now for PostGIS is to reach SFSQL compliance. If 
it is not in the spec, then I would suggest that you could try to implement it 
yourself, I'm sure we would include such a function in the distribution, if you 
sent it to us.

Later,
Chris
