I've managed to reproduce this: the triggering condition is that a
single autovac iteration has to VACUUM one table and then ANALYZE
(no vac) another table that has an expressional index with a plpgsql
function. It looks like we missed a path of control where
ActiveSnapshot has to be re-set-up, but I'm not clear where.
