Having revisited the configuration page I see that the concept of table prefix has been covered. Perhaps some arrangement could also be made so the version info table can be placed in a different schema or tablespace? Perhaps the prefix in this case is not the best configuration option. Maybe another option for schema would be appropriate.
Appologies for a bogus post.
A work-around would be to create the tables yourself in a different schema, then add synonyms in one schema to the other. This is what I often see done with Oracle.
Hopefully, "adamw" will work on creating that SVN repository and JIRA list, and maybe attract a few volunteer hands to work on things like this. Adding a version schema option would be a pretty easy thing for a contributor to add.
sorry for the slow replies, but I'm travelling this week and the next, so I have limited time.
About the SVN - it's coming. In fact, the repository is created, but I don't have write access to it ;). And you can just call me Adam, instead of "adamw" :). Contributions are of course always welcome, even when the SVN is not there, you can always send a patch (the latest dev sources are on the downloads section on the page).
About the tablespace/catalog/etc: it's certainly possible, and it's also certainly a useful feature. So it will come sooner (when there's a contributor, hopefully) or later (when I'll do it myself) :).
