The MaxAllocSize guard is convenient for most callers, because it reduces the need for careful attention to overflow, data type selection, and the SET_VARSIZE() limit. A handful of callers are happy to navigate those hazards in exchange for the ability to allocate a larger chunk. Introduce MemoryContextAllocHuge() and repalloc_huge(). Use this in tuplesort.c and tuplestore.c, enabling internal sorts of up to INT_MAX tuples, a factor-of-48 increase. In particular, B-tree index builds can now benefit from much-larger maintenance_work_mem settings. Reviewed by Stephen Frost, Simon Riggs and Jeff Janes. |
