I think those messages are just hung up in moderation. If you're
not subscribed to pgsql-bugs, whatever you send will be held for
moderator approval (a sadly-necessary spam defense).
Anyway, the error is coming out of this bit:
,qoffs as (
select
...
,(((((ra -(select ra_base from qsum))*1000000000000)::bigint)>>15)&((1::bigint<<31)-1))::int as ira
...
"(select ra_base from qsum)" certainly is a "sub-select used as an
expression", and I guess the difference between your smaller and
larger datasets is how many rows the qsum CTE produces. If I'm
reading it right, that'll produce one row for each distinct value
of "(source_id >> 35+12)&((1<<16)-1)".
