In Magento 1.8.0, the flat product and flat category indexes have been removed.

enter image description here

Does Magento 1.8 no longer support the flat product and category tables? If Magento 1.8 does support the flat product and category tables, how are these table created and populated?

  • product_flat_store and category_flat_store tables are generated and populated, so they seem supported. No triggers in DB, so it must be indexer code, but hidden away Oct 8, 2013 at 19:08

Starting with Magento CE 1.8 the flat table indexes are only shown on the Index Management page if flat tables are enabled.

Enable flat tables in System > Configuration > Catalog > Catalog > Frontend:

Enable flat tables

Enjoy the flat table indexes in System > Index Management:
