Hi,

I'm not sure what is causing this, but I have seen this twice. The
second time without activity after changing the set of tables in a
PUBLICATION.

gdb says that debug_query_string contains:

"""
START_REPLICATION SLOT "sub_pgbench" LOGICAL 0/0 (proto_version '3', publication_names '"pub_pgbench"')START_REPLICATION SLOT "sub_pgbench" LOGICAL 0/0 (proto_version '3', publication_names '"pub_pgbench"')
"""

attached the backtrace.
