Comments:
1) We have a different syntax to the SQL200n draft (and Oracle by the
looks of it) for ROLLBACK. The draft says:
> <rollback statement> ::= ROLLBACK [ WORK ] [ AND [ NO ] CHAIN ] [ <savepoint clause> ]
> <savepoint clause> ::= TO SAVEPOINT <savepoint specifier>
2) We have a different syntax for RELEASE too. The SQL200n draft says:
> <release savepoint statement> ::= RELEASE SAVEPOINT <savepoint specifier>
3) Can the command tag for a ROLLBACK TO SAVEPOINT be different to the
command tag for a global rollback, so clients can distinguish the two
cases? ("ROLLBACK <savepoint specifier>" might be nice)
