At first I thought the lack of context indicated a palloc had failed during

pg_stat_statements that's less than ideal. Attached patch fixes, though I'm
not sure if %lld is portable or not.

Oops. I'll fix that and address David's concern tomorrow.
I'm not opposed to this basic idea, but I think the message should be
reworded, and that the presence of two separate ereport() call sites
like the above is totally unnecessary. The existing MaxAllocSize check
is just defensive; no user-visible distinction needs to be made.
I disagree. If you're running this on a 200+GB machine with plenty of
free memory and get that error you're going to be scratching your head.
I can see an argument for using the OOM SQLSTATE, but treating an
artificial limit the same as a system error seems pretty bogus.
