Cargo Features

[dependencies]
dbmigrator_cli = { version = "0.4.1", default-features = false, features = ["postgresql"] }
default = postgresql

The postgresql feature is set by default whenever dbmigrator_cli is added without default-features = false somewhere in the dependency tree.

postgresql default = tokio

Enables tokio-postgres of dbmigrator

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
