 Some functions take a lot of time or memory, but aren't interruptible.
 See #1799 for an example of function within postgis, but most notably GEOS
 implemented functions have this problem.

 This ticket is to find a way to ensure interruptability of the functions.

 So far it looks that calls to elog (thus lwnotice, for example) is one
 such chance of interruptability.
