Sure they do.  They had better, else (for example) the associated index
insertions will be wrong.

True, but in most places it would uglify the code quite a bit to make it
like that, because START/END_CRIT_SECTION are bracketing code that is
shared between both cases.  And I'm not seeing where we'd get any
particular reliability gain from it: if the code has any significant
risk of elog'ing during the critical section, it's broken anyway ...
