(bug 27283) SqlBagOStuff breaks PostgreSQL txns
* SqlBagOStuff should not turn off automatic transaction
control just like that. Keep previous
connection for PostgreSQL and SQLite
*
94633ff448e9253c5503124df6748be1fc26b8e2 introduced
rollback on error to restore sanity
for the connection. Don't do this
if you are in the middle of INSERT IGNORE
and we have a savepoint open.
Making sure query syntax errors don't
get silenced by our "wonderful" implementation
of INSERT IGNORE is bug 35572.
