Sure. Do we have the draft somewhere to copy-paste from? Or do you
copy-paste it from the previous one manually removing unneeded lines?

I think there is no way to introduce trees in migration chains until
the following alembic is implemented and released:

Mike, is it correct?

The SQL statement for this is: "ALTER TABLE agents ADD CONSTRAINT
uniq_agents0agent_type0host UNIQUE (agent_type, host);" Will it be
enough, or should we instead implement some script using sqlalchemy to
stay on portable side (and maybe even place it in tools/ directory
shipping with the package)?

[Note: I have no idea how portable the statement above is.]
