Обсуждение: Shouldn't psql -1 imply ON_ERROR_STOP?

When you run a file with psql -1/--single-transaction, and a command fails, 
you get bombarded with

ERROR:  current transaction is aborted, commands ignored until end of 
transaction block

for the rest of the file.

Shouldn't -1 imply ON_ERROR_STOP or some variant by default?

That would certainly be useful.

Personally I'd prefer it to default to that always, and not just in
-1, but that would break way too many old things I'm afraid...

Doing it always would be really annoying.  I often reload dumps that
fail the grant statements but otherwise work.  Admittedly, if I
planned ahead, I could avoid having the grants be present in the
dumps, but that would require planning ahead...

But +1 for doing it when -1 is used.

Sounds reasonable, +1 from me.

Only if it could ensured that embedded SAVEPOINTS can be handled 
properly...a quick check shows that ON_ERROR_STOP will stop any script even 
when the errorneous command is probably rolled back by a subsequent 
ROLLBACK TO:

SELECT 1;

SAVEPOINT A;

SELECT et; <-- ON_ERROR_STOP stops here

ROLLBACK TO A;

SELECT 2;

It seems -1 needs some smarter variant of ON_ERROR_STOP.
