Sorry for coming into this discussion late. I think this is an excellent set of patches. I had developed a similar enhancement to allow mod_dbd to connect with multiple databases at my last job but never had a chance to make it available here. Your version is far more clever and configurable.
I did have one minor nit to pick with the implementation of the DBDInitSQL command. A user might presume that the order of commands listed in the config file would be preserved when the commands are run. By using a hash table, you'll likely get a random order causing problems. For example, perhaps the user needs to first load one table then choose a subset from that first table to file another; if you run them in the reserve order, the second table will likely be empty. :( If you choose not to change the implementation, then the documentation should make this clear.
