Hi,

I use slony 1 v 1.2.14.

After an unexpected stop, several tables remained locked :

sl_log_1 -> RowExclusiveLock,
sl_log_status -> AccessShareLock,
sl_action_seq -> AccessShareLock,
h_jou_pmvdata -> RowExclusiveLock (data table).

This has happened a couple of times, even though I don't have a way to
reproduce it. A database restart does not help. Because of these locks, I
can't get rid (truncate / delete) of the tables nor even dump the db.

Only solution : destroy and rebuild from the master database (it is
replicated after all).

I would be glad to send any information needed to investigate.
