I have data (from an external source) which is in text format as a hex number (it's actually an IP address, but that's probably not relevant.)
to_hex gets from integer to hex, I can cast a hex constant to integer (ie x'12a7'31'::int, but how do I get a database column from string/hex to integer?
(If this is referenced in the documentation, I'm not finding it.) -- Mike Nolan
