Hello,

we are using gin indexes on big tables. these tables happen to have several billion rows.
the index creation fails in ginCombineData in src/backend/access/ginbulk.c because repalloc is limited to 1 gb.
this limitation makes no sense in this context (compare comments in src/include/utils/memutils.h).
To overcome this limitation on tables with lots of rows repalloc_huge is used.
The test suite still succeeds on my machine.
Find the patch attached,

Kind regards,

Robert Abraham
