I&#x27;m no expert but in my (limited) experience, there are some super handy datatypes and features that PostgreSQL supports that MySQL doesn&#x27;t:<p>- Arrays, particularly with GIN indexes. This makes things like tagging <i></i>fantastic<i></i> in Postgres. Instead of putting your tags in another table, you throw them in an array and you can do all kinds of things like set intersection-like queries.<p>- JSON. Postgres can store data as JSON and index and query the JSON. This essentially gives you MongoDB type queries.<p>I&#x27;m sure there&#x27;s more but these are my favourite Postgres features.
