Thank you for responding so quickly. I'm comfortable with "heap." On the other hand, src/backend/access/brin/README uses "table" as follows. Second, I thought users would feel more familiar with the general term "table." Third, I supposed PostgreSQL might add support for other structures for tables than heap in the future, like SQL Server provides heap (non-clustered table) and clustered tables.

At index creation time, the whole table is scanned; for each page range the
summarizing values of each indexed column and nulls bitmap are collected and
stored in the index.

I should have written the reason I chose "table." Anyway, I'm OK with heap.
