IMPORTANT: Functions must always return NULL in place of '''' (the empty string). This ensures that empty strings do not find their way into VegBIEN.

NOTE: SQL-language functions should never be declared STRICT, because this prevents them from being inlined. inlining can create a significant speed improvement (7x+), by avoiding function calls and enabling additional constant folding. avoiding use of STRICT also makes functions *much* easier to troubleshoot, because they won''t mysteriously do nothing if called with only NULL arguments, even when you have added debug-print statements.
