Hmm... I've read that now (thank you!) and I have added:

$acw=$DB->{AutoCommit};
print " |- AutoCommit was: [$acw]\n";
$DB->{AutoCommit} = 0 || die...
$acn=$DB->{AutoCommit};
print " |- AutoCommit now: [$acw]\n";
$DB->begin_work() || die...
#lot of transactions
$DB->commit() || die...

For some reason though my program dies on the '$DB->{AutoCommit}=0 ...'
line. I usually print '$DBI::errstr' in the 'die' to see what happened
but that is blank. I read in that section that some databases simply
don't support turning off AC and will die with a fatal error if you try
to turn it off. Could this be what is happening? If so, shouldn't there
be a more verbose error? Also, I know pgSQL supports AC being turned off
because I first read about this feature in there docs. Am I making an
mistake?

Many thanks!

Madison
