Ok, here is a full patch that includes:
- all what was in the previous patch
- GUC vars are rolled back on subxact abort
- the inval msg lists are cleaned up of items created in the aborting
subxact
- SET CONSTRAINTS is rolled back too
Missing:
- all the other items Tom mentioned in his last mail, including
performance enhancements.
- discussion whether we want a different syntax for subxacts, like
SUBBEGIN/SUBCOMMIT/SUBABORT instead of BEGIN/COMMIT/ABORT. Please
comment on this point.
- support for SAVEPOINT syntax.
