Our main database is already running on PostgreSQL 13 (anything in the “12.x or higher” family), and I need an experienced DBA to step in and tighten two things: First, Database optimization. The work includes reviewing current configuration parameters, checking execution plans, tuning indexes, and suggesting any schema changes that will noticeably reduce latency under peak load. If extensions (pg_stat_statements, auto_explain, etc.) should be enabled or configuration values (shared_buffers, work_mem, effective_cache_size and friends) adjusted, please make those recommendations backed by data. Second, Backup and recovery. I want a clear, scripted process—preferably with pg_dump and/or a modern tool such as pgBackRest or Barman—that covers daily backups, poi...
