Change the format of TRX_IDs in INFORMATION_SCHEMA tables from DEC to HEX. The current TRX_IDs are hard to remember and track down: 426355, 428466, 428566, etc. In HEX: * there are less "digits", the strings are shorter; * since there are 16 instead of 10 "digits", the chance of having repeating ones are smaller. The above look like 68173, 689B2, 68A16 in HEX. Discussed with: Ken Approved by: Heikki (via IM)
