Обсуждение: reordering sequences

> is it at all possiable to reorder a squence? I'm finding that our
sequences get some what out step and messed and would like to ocassionaly
reorder them, though I'm unable to find anything that might be able to do
this.

BEGIN;
SELECT setval('MyTable_MySeq_SEQ',1);
UPDATE MyTable SET MySeq=nextval('MyTable_MySeq_SEQ');
COMMIT;

Of course this will screw up any foreign keys that you have that don't have
an ON UPDATE CASCADE set on them. Also, this is not guaranteed to preserve
the current sequence order, if that's important to you.

In my logs, I find a lot of these:

    NOTICE:  current transaction is aborted, queries ignored until end of
transaction block

should I be concerned?  Is there a place where I can read about the
difference messages that may appear in the log file?

Thanks!
