Good.  Now that I think of it, nested transactions don't seem required. 
We already allow pg_dump to dump a database using INSERTs, and we don't
put those inserts in a single transaction when we load them:CREATE TABLE "test" (        "x" integer);INSERT INTO
"test"VALUES (1);INSERT INTO "test" VALUES (2);
 

Should we be wrapping these INSERTs in a transaction?  Can we do COPY
with each row being its own transaction?
