Ahh, so the reason I didn't see these crashes is that Atsushi had
already fixed them. Nice. It would be *very* good to trim the quoted
material when you reply --- don't leave everything, just enough lines
for context. I would have seen this comment if it didn't require me to
scroll pages and pages and pages of useless material.
I have pushed this patch from 9.4 to master. I reformulated the
comments.
This is an "implicitly aborted transaction":
alvherre=# create table implicit (a int);
CREATE TABLE
Duración: 0,959 ms
alvherre=# insert into implicit select 1/i from generate_series(5, -5, -1) i;
ERROR: division by zero
Note there is no explicit ABORT here, so it is implicit.
But that is not what you were trying to say. The term "crashed
transaction" seems to me to convey the meaning better, so I used that.
