The initial replication of all 165 tables appears to succeed.  When 
slony tries to replicate the first sequence, the following error is 
reported:

I've created a 2-node cluster using the following slonik scripts:
preamble.slonik:
cluster name=cluster_1;
NODE 1 ADMIN CONNINFO = 'dbname=mydb host=host1 user=xxxx password=yyyy 
port=5432';
NODE 2 ADMIN CONNINFO = 'dbname=mydb host=host2 user=xxxx password=yyyy 
port=5432';

01-create_nodes.slonik:
include </home/foo/slony-setup/preamble.slonik>;
init cluster (id=1, comment='cluster_1 master');
store node (id=2, comment='cluster_1 subscriber');

02-store_paths.slonik:
include </home/foo/slony-setup/preamble.slonik>;
STORE PATH (SERVER=1, CLIENT=2, CONNINFO='dbname=mydb host=host1 
user=xxxx password=yyyy port=5432');
STORE PATH (SERVER=2, CLIENT=1, CONNINFO='dbname=mydb host=host2 
user=xxxx password=yyyy port=5432');

03-create_set.slonik:
include </home/foo/slony-setup/preamble.slonik>;
create set (id=1, origin=1, comment='cluster_1 Tables and Sequences');
# TABLES
set add table (set id=1, origin=1, id=1, full qualified name = 
'mydb.fs_category', comment='Table dependency level 0');
set add table (set id=1, origin=1, id=2, full qualified name = 
'mydb.fs_setting', comment='Table dependency level 0');
set add table (set id=1, origin=1, id=3, full qualified name = 
'mydb.fs_value', comment='Table dependency level 0');
set add table (set id=1, origin=1, id=4, full qualified name = 
'mydb.finch_user', comment='Table dependency level 1');
set add table (set id=1, origin=1, id=5, full qualified name =

set add table (set id=1, origin=1, id=6, full qualified name = 
'mydb.adb_marker', comment='Table dependency level 2');
set add table (set id=1, origin=1, id=7, full qualified name = 
'mydb.adb_sample', comment='Table dependency level 2');
<snip>
# SEQUENCES
set add sequence (set id=1, origin=1, id=1, full qualified name =

set add sequence (set id=1, origin=1, id=2, full qualified name =

'mydb.email_seq', comment='');
set add sequence (set id=1, origin=1, id=6, full qualified name = 
'mydb.faddress_seq', comment='');
<snip>

** Note that there are a total of 165 tables and 100 sequences added to 
the set.

04-subscribe_set.slonik:
include </home/foo/slony-setup/preamble.slonik>;
subscribe set (id=1, provider=1, receiver=2, forward=yes);

I also tried adding the sequences to the set by starting their id values 
with 1001, but that got me the same results. 

Thanks in advance for your time and help!
