 I've discovered that calling:
 {{{
 SELECT (SRF())*;
 }}}

 Calls SRF() once for each column in output.
 As of version 8.4 this also happens if SRF() is defined as STABLE (didn't
 check the IMMUTABLE case).

 It should be checked if ST_Dump suffers from this and carefully
 look for its uses (there should be a few in topology)
