Actually the view isn't as intricate as I thought, but I'd like to avoid
publishing it for sake of simplicity.  I replaced the view with its underlying
table and now I get:

[pryzbyj@database ~]$ time psql ts -f tmp/sql-jit-crash-2018-11-15.jtp 
psql:tmp/sql-jit-crash-2018-11-15.jtp:12: ERROR:  invalid memory alloc request size 2447889552

It's unclear if that's a useful hint, a separate problem, or a nonissue..
