Oh, sorry, not enough caffeine yet --- somehow I was thinking about
pg_stat_statements not auto_explain.
However, auto_explain is even worse on the other problem. You flat out
cannot do catalog lookups in a failed transaction, but there's no way to
print a decompiled plan without such lookups. So it won't work. (It
would also be appropriate to be suspicious of whether the executor's
plan state tree is even fully set up at the time the error is thrown...)
