My initial idea was to ask for a DBI:: namespace, but yesterday I found out that such namespace is restricted. Then DBIx:: is a good candidate (Or it should be as soon as I get an answer from CPAN. Being in a monastery, I should become used to being patient {grin}).
DBIx::DBSchema was a good hint. I checked it and it seems to provide enough information to replace the direct calls I am using so far.
I would need to rewrite the two subs that are dealing with column information (so many greps and maps wasted!) but this is a good chance to make the module portable across databases.
Thanks.
