No, it's more widely used than that, and we're using it with the
standard meaning AFAIK:


https://docs.microsoft.com/en-us/sql/relational-databases/indexes/heaps-tables-without-clustered-indexes?view=sql-server-2017
http://docs.actian.com/ingres/10.2/index.html#page/DatabaseAdmin/Heap_Storage_Structure.htm

It just means tuples stored in no particular order (as opposed to eg
btree tables, in systems that support those).
