Comment(by strk):

 From http://www.postgresql.org/docs/8.3/static/spi-visibility.html

 {{{
 All standard procedural languages set the SPI read-write mode depending on
 the volatility attribute of the function. Commands of STABLE and IMMUTABLE
 functions are done in read-only mode, while commands of VOLATILE functions
 are done in read-write mode. While authors of C functions are able to
 violate this convention, it's unlikely to be a good idea to do so.
