Here is the documentation for Data Managers:

https://galaxyproject.org/admin/tools/data-managers/
https://galaxyproject.org/admin/tools/data-managers/data-manager-xml-syntax/
https://galaxyproject.org/admin/tools/data-managers/data-manager-json-syntax/

I don't see any reference to removing entries from a Tool Data Table. Is
there a technical reason why it can't be done?

As I understand it, each Tool Data Table must have one column called
'value' that acts as a unique ID for that row of the table. So the data
manager would just need the name of the Tool Data Table and a string to
look up in the 'value' table, and it would remove that row if it found a
match.

In my case, another column in the Tool Data Table stores the path to a kmer
database that should be removed from the disk.

Will this be possible with the currently-available xml & json syntax? Are
there any postgresql database entries that should be cleaned up if a Tool
Data Table entry is removed? Is there some reason why this is a bad idea or
is there another way of accomplishing this (removing Tool Data Table
entries) that I've missed?

Thanks

Dan
