[postgis-devel] Function names in PostGIS

I had the same thought too, but thought it would be too confusing to people to go back and change all those so didn't care to voice the concern.  Moving forward is a good idea I think.

It is confusing to have things like ST_Dump() and realize it really isn't an SQL/MM function.  I noticed when looking at SQL Server 2008 - that the functions that are not part of the spec they did not prefix with ST.. so it is easier to tell when you are using proprietary stuff.

Regarding function names in PostGIS.

I was wondering if it would be a good idea to reserve the
"ST_" prefix for SQL/MM functions?
This would make it easier for users to know when they are
using "standard" functions and when they are using (the less
portable) PostGIS functions.  It would also save us trouble
if SQL/MM should introduce new a function with the same name
as a PostGIS function, but with different semantics.

Just a thought...
