 It also seems to rely on GDAL so not sure if that is an additional
 dependency we need to compile in to expose this or not.

 Hi Regina,

 We don't have a SQL function yet, only a core C function. I'll create a
 SQL function ASAP. Sorry for delay, but I was involved in a different
 project (and studying) until 2 days ago. And the C function relys on GDAL,
 yes, but only if you specify the "--enable-development" option during
 configure. If not, a "dummy" function that only returns 0 is compiled. We
 may change this in the future.

 Best regards,
 Jorge
