Passing list parameter to raw SQL query

[Real-Gecko]

I need to call a stored procedure from Postgres, procedure params look like this:

CREATE PROCEDURE import_metadata(IN table_name TEXT, IN headers ARRAY, IN metadata_file_path TEXT)

But as I use execute method like this

table_name = 'metadata'
headers = ['ID', 'first_name', 'last_name', 'gender', 'age', 'address', 'language']
metadata_file_path = '/path/to/metadata.csv'

db.execute("call import_metadata($table_name, $headers, $metadata_file_path)",
  {
    table_name: table_name,
    headers: headers,
    metadata_file_path: metadata_file_path,
  },
)

I get an error: TypeError: unhashable type: 'list'
Is it really possible to pass lists to raw SQL queries?
