[postgis-devel] RETURNS TABLE - SRF

Is there anything I should know about set-returning functions
in terms of policies before starting to implement one ?

So far I've been creating types and returning SETOF <created_type>,
like with ST_Dump for instance. But since 8.4 PostgreSQL also supports
anonymous TABLE returns, which _might_ be a better choice to reduce

So, are there known reasons _not_ to use the 8.4 RETURNS TABLE syntax ?
