We use Oracle here at work.  I'm currently using the
Postgresql backend, but for this to be rolled out
company wide, I will probably need to have an Oracle
backend.  I started creating an Oracle backend, but ran
into the issue that Oracle (and I believe SQL Server)
does not like tables that begin with an underscore. 
What I thought I could do is create a new rdbms
configuration entry that defaults to an underscore but
would be used as the prefix for the underscore entries
(tables, indexes, etc).  This would allow the user
table to be something like RNDUP_USER or even S_USER
which Oracle can handle.  I started my Oracle backend
based on the Postgresql backend and was able to get it
to work until it hit the first underscore.  If this is
something that is desired, I do not mind looking into
the required changes across the board to implement the
Oracle interface.
