 Indexes can consume a significant amount of disk space

• Evaluate the necessity of each index. Consider dropping unused or redundant indexes.
• Periodically reindex tables with REINDEX to reclaim space used by fragmented indexes.

I wanted to update you on the current disk space usage for the PostgreSQL database. The total disk space allocated is 236 GB, of which:

• 184 GB is occupied by tables.
• 27 GB is consumed by indexes.

identified the following large tables that are significantly contributing to the overall disk space consumption:

These tables, along with the associated indexes, are the primary drivers behind the current storage utilization.

To ensure that the database continues to operate efficiently and that disk space is used optimally, I recommend performing regular maintenance tasks, such as:

• Vacuuming: To reclaim storage occupied by deleted rows and optimize the performance of the database.
• Reindexing: To rebuild indexes and ensure they are stored efficiently.
• Archiving old data: Consider moving old or less frequently accessed data to a different storage tier if possible.
