Greetings,

We're using 4.99.7 with PG 9.1.5 and seeing the syncrun table growing 
without bound with old (ie, ended) records, eg:

    $ psql -Ubucardo bucardo -c 'select count(*) from syncrun'
    count
    --------
      969759
    (1 row)

    $ psql -Ubucardo bucardo -c 'select count(*) from syncrun where
    ended is null'
      count
    -------
          0
    (1 row)

    $ psql -Ubucardo bucardo -c 'select * from syncrun limit 4'
       sync   | truncates | deletes | inserts | conflicts |           
    started            |             ended | lastgood | lastbad |
    lastempty | details | status

    f       | f         |         | No delta rows found (KID 2293)
      lg_sync |         0 |       1 |       1 |         0 | 2013-05-14
    00:47:02.276394+00 | 2013-05-14 00:47:02.288491+00 | f        |
    f       | f         |         | Complete (KID 2293)
    (4 rows)


My workaround might be to add a periodic cleanup job, ie, 'delete from 
syncrun where ended is not null' every 10 min or so but I'd rather fix 
the root cause instead.
Anybody seen this?

Thanks.
