Perhaps you should check the archives where this was discussed (it
took shape late last year).  And the mod_dbd page at httpd.apache.org
and its references.  And reflect on why, in the absence of apr_dbd
in earlier httpd versions, there are so many *different* modules each
making their own SQL connections.

I'm not familiar with libsdb.  Currently we have a fairly simple
string-based layer.

We've had a libdbi-based connection pooling module for some time.
The native APR layer is better-fitted to our architecture.
