Removal of indexer/postgres from main branch #25389
Description
I noticed that the cosmossdk.io/indexer/postgres functionality, which used to provide a PostgreSQL indexer for module state, has been removed from the main branch in the latest version.
I have a few questions regarding this change:
1. Could you clarify the reason for removing the PostgreSQL indexer?
2. Is there a recommended alternative for indexing module state into PostgreSQL or another database?
3. Are there plans to reintroduce a similar indexing feature in future releases?
This functionality was quite useful for applications that need to query module state efficiently, so any guidance on how to achieve similar functionality would be appreciated.
Thank you for your time and for the great work on Cosmos SDK!
