title: How to list all indexes of a table with their corresponding size in PostgreSQL?
body: <p>I can view the total size of all indexes in a table with</p>
  <p><code>SELECT pg_size_pretty (pg_indexes_size('table_name'));</code></p>
  <p>and the size of a specific index with:</p>
  <p><code>select pg_size_pretty(pg_relation_size('index_name'));</code>,</p>
  <p>but I would like to retrieve a list with size information for each index of the table separately <em>(a list of index sizes with the corresponding index name they belong to)</em>.</p>
