What are advanced data types in asyncpg?

Advanced data types in asyncpg include JSON, arrays, hstore, and composite types, allowing for complex data handling.

Can you give me an example of using JSON data type?

Sure! You can store a JSON object in a PostgreSQL column and retrieve it using asyncpg like this: await conn.fetch('SELECT data FROM my_table WHERE id=$1', id).

How do I handle arrays in asyncpg?

You can use the ARRAY type in PostgreSQL. For example, to insert an array: await conn.execute('INSERT INTO my_table(arr) VALUES($1)', [1, 2, 3]).

What is hstore and how do I use it?

Hstore is a key-value store within a single PostgreSQL column. You can use it by defining a column as hstore and inserting data like this: await conn.execute('INSERT INTO my_table(data) VALUES($1)', {'key': 'value'}).
