COMMENT ON SCHEMA util IS '

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.

COMMENT ON FUNCTION "cast"(value text, ret_type_null anyelement) IS '

allows casting to an arbitrary type without eval()

usage:

SELECT util.cast(''value'', NULL::integer);

note that there does *not* need to be a cast from text to the output type,

because an INOUT cast is used instead
