Your PostgreSQL database is growing, but you can reduce its size by implementing several strategies. First, consider using Timescale compression to compress data and save storage space. Monitoring dead tuples in each table is also crucial to minimize storage usage. Running autovacuum more frequently can help free up wasted storage space. Reclaiming unused pages with pg_repack and finding unused indexes are also essential steps. Arranging columns by data type from largest to smallest can minimize unnecessary padding, and deleting old data regularly helps maintain a healthy database size. By implementing these techniques, you'll be able to reduce your PostgreSQL database size sustainably.
