will post_id ever change? Can I safely use post_id for custom queries?

Post ID’s do not change. The reason behind this is the ID column in MYSQL is the primary key for the table. It is auto incremented when a new row is added. It is improbable that a post ID would change programatically unless someone is doing something rogue in the database.
