Multiple database + pconnect issues

The only 1:1 choice for serialization is a multi-dimensional array (which I prefer just as a matter of personal preference), but as far as I can tell either you have the inconvenience of a method call or the inconvenience of multiple levels of indirection.

I see what you mean about the extra parameters things now -- you can't force a new persistent mysql connection. But the next question is...does it matter? If you look at db_pconnect in the CI postgre driver, you can't force a new connection (..yet). Same for ms sql. So perhaps just storing the particular database with respect to a particular combination of parameters would be enough...

The last question is...what if the SQL server "goes away" in the middle of a script. Can that happen? Otherwise the connection might get reestablished and the db_select method will still think the old database is selected.
