add option: --write-header
we can omit the relation's header and generate just the records
and append them to an existing relational stream:
(relpipe-in-cli --relation rrr --attribute a integer; relpipe-in-cli --write-header false --relation rrr --attribute XXX integer --records 1 2 3) | relpipe-out-tabular
