My solution to provide total platform agnosticism (not in Perl, BTW, but the solution still applies) was to skip the assorted platform specific autoincrement features and roll my own, using a single row/single column table to hold an integer used as a unique ID on all insert statements.

The pseudo-code would look something like this: 
sub insertRecord {
  my $newRow = shift;
  my $id = getSequence;
  execute "insert table (id, data) values ($id, $newRow);";
}

sub getSequence {
  my $seq = execute "select id from sequenceTable;";
  #now increment sequence
  execute "update sequenceTable set id = id + 1;";
  return $seq;
}

where sequenceTable has a single integer column called "id".

It's neither pretty or very efficient (I certainly wouldn't recommend it for a high- or even medium-volume multiuser environment), but it will work on any database platform which implements the most basic of SQL commands.
