Hello,
Pgpool executes "SELECT * FROM pg_stat_replication" to retrieve
replication_state and replication_sync_state.
Could you try to connect to PostgreSQL primary using pgpool user
and run "SELECT * FROM pg_stat_replication"
on the server where pgpool is running?
psql -h <PostgreSQL primary> -U pgpool -p <PostgreSQL port> -c "SELECT * FROM pg_stat_replication"
