With the risk to forget important improvements, here's my list of new features which could be important at the level of tables and datatypes:
  • Identifier length limits have increased (often to 128 bytes)
    like column name, schema name, trigger name.
    (Note that it's bytes, not characters; e.g., when using UTF-8 encoding for the catalog, "normal", non-accented letters are 1 byte but accented letters, Greek, Cyrillic etc. are 2 bytes and characters from most other alphabets are 3 (and sometimes 4) bytes.)
  • The "SET" statement can now be used "anywhere", esp. in a prepared statement, possibly even with parameter markers.
  • DECFLOAT is a new datatype. Great stuff, check it out!
    (or come to my presentation at IDUG Rome, if it gets accepted)
  • Some new (names for existing) scalar functions, for Oracle compatibility, like NVL and DECODE, and new scalar functions for bit operations (BITAND() etc).

Caught my eye too. This EXCELLENT feature has been around for some time.
What they should add is the possibility to pass this kind op parameters (also COMPRESS) to the backup-command generated by the"autmatic maintanance".
