Cargo Features

[dependencies]
db-helpers = { version = "1.5.0", default-features = false, features = ["pg"] }
default = pg

The pg feature is set by default whenever db-helpers is added without default-features = false somewhere in the dependency tree.

pg default = tokio-postgres

Enables pg of db-helpers-derive

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.
