maintenance_work_mem is what would be used for CREATE INDEX.
FWIW, though, the combination of this weird error and the fact that you
had a corrupt index to begin with makes me suspicious that there's some
low-level problem. You might be well advised to do some memory testing
on that machine, for example.
