experts,
    we faced into a lot of  lwlock:LockManager wait-events , all of these
queries are "select ..." ,  there are other several session are doing DML,
insert/update/delete on same table.   Did these DML transactions holding
"transactionid" and "tuple" lock blocking "select" on lwlock:LockManager ?

Thanks,

James
