Thank you .
I was thinking the individual statement will work fine if I pull out those
from the begin..end block, as those will then be not bounded by any outer
transaction.
 However, When I was trying it from dbeaver by extracting individual index
creation statements rather from within the "begin ..end;" block, it still
failed with a different error as below. Why is it so?

 "SQL Error [25001]: Error: create index concurrently cannot be executed
within a pipeline "
