What's this?

remove_exclusion_constraint(table_name, expression = nil, **options) public

Removes the given exclusion constraint from the table.

remove_exclusion_constraint :products, name: "price_check"

The expression parameter will be ignored if present. It can be helpful to provide this in a migration’s change method so it can be reverted. In that case, expression will be used by #add_exclusion_constraint.
