Hi Vignesh,
I found that when 2 subscriptions are both subscribing to a
publication publishing sequences, an ERROR occurs on refresh.
======
Publisher:
----------
test_pub=# create publication pub1 for all sequences;
Subscriber:
-----------
test_sub=# create subscription sub1 connection 'dbname=test_pub'
publication pub1;
test_sub=# create subscription sub2 connection 'dbname=test_pub'
publication pub1;
test_sub=# alter subscription sub1 refresh publication sequences;
2024-08-12 15:04:04.947 AEST [7306] LOG: sequence "public.seq1" of
subscription "sub1" set to INIT state
