yeah, i would not expect that to work.  there are also a lot of other parts in the code that have stuff like test "$dbc_dbtype" = "mysql" etc.

i have two suggestions, both of which would work with the current version of dbconfig-commont:

(a) put some logic in your config file.  that is, you could easily modify your config file so that it sets the appropriate value:

<?php 
	if($dbtype == "mysql") { $dbtype = "MYSQL"; } 
	else ...
?>

or

<?php
	$dbtype = strtoupper($dbtype);
?>

(b) use dbconfig-common's template output to generate a temporary output file, and then pipe it through sed and ucf-register it yourself in your postinst

#!/bin/sh -e
....
dbconfig-generate-include -f template -o template-outfile=sometmpfile /etc/dbconfig-common/yourpkg.conf
sed -i -e 's/mysql/MYSQL/g' -e ... sometmpfile
ucf sometmpfile /etc/where-it-goes.php
