3-Perspective Series
Complex database challenges cannot be resolved through a single lens. A unified technical series covering the same problem across three disciplines: Deep Engine Triage (dbaguide), Tool Selection (dataxtools), and SRE Incident Response (dataopsphere).
PostgreSQL Locks, Deadlocks & Long Transactions: Diagnosis, Tool Selection & Incident Response
Complementary 3-site technical triad addressing PostgreSQL lock queues, deadlocks, and long transactions across three disciplines: deep diagnosis and verified L1-L5 empirical lab results (dbaguide), tool selection matrix from CLI to continuous APM (dataxtools), and incident management discipline with RACI and fillable incident response card (dataopsphere).
Reading PostgreSQL Locks: Blocking, Deadlocks and Long Transactions
PostgreSQL lock hierarchy, identifying root blockers with pg_locks and pg_stat_activity, empirical L1-L5 lab proofs, and safe termination guidelines.
Choosing PostgreSQL Lock Observability: From Live Sessions to Historical Evidence
Comprehensive evaluation of native CLI/views, real-time curses dashboards, and historical telemetry platforms for PostgreSQL lock wait diagnostics.
Running a Lock-Wait Incident: Ownership, Intervention Decisions and Recovery Evidence
Managing lock contention crises without panic: RACI ownership, controlled rollback/terminate decisions, retry storm mitigation, and recovery evidence.
PostgreSQL Connection Capacity & Connection Pooling: Triage, Tool Selection & SRE Capacity Budget
Complementary 3-site technical triad covering connection saturation and pooling from three distinct disciplines: deep diagnosis and read-only pg_stat_activity (dbaguide), two-tier pooling and PgBouncer transaction mode tradeoffs (dataxtools), and mathematical capacity budgeting with rolling deployment surge (dataopsphere).
PostgreSQL Connection Management: Lifecycle, Capacity, and Pooling
Full connection lifecycle from client to backend process, active/idle resource overhead, max_connections bounds, two-tier pooling, and safe baseline configurations.
Which Need Does PgBouncer Solve Alongside Application Pools?
Application pools and PgBouncer are complementary. Mode constraints, prepared statements, and session state management.
Protecting Connection Budgets During Application Scaling
Mathematical backend budget formula as app instances scale, rolling deployment surge management, exponential backoff, and on-call runbook.
PostgreSQL Replication Lag: Diagnostics, Tooling Evaluation & Incident Escalation
Complementary 3-site content set covering replication lag from 3 angles: deep diagnosis (dbaguide), tool evaluation (dataxtools), and SRE incident escalation (dataopsphere).
PostgreSQL Replication Lag: Step-by-Step Bottleneck Diagnosis
Replica falling behind? Is the bottleneck in WAL generation, network transfer, or replay? Identify the exact stage where replication lag accumulates using safe, read-only diagnostics.
Replication Lag Monitoring: What to Look for in Tools?
postgres_exporter vs Percona PMM: Telemetry reliability, idle system metrics, and pilot evaluation rubric.
From Replication Lag Alert to Incident Response
7-step on-call response protocol, pre-filled service scorecard, business impact matrix, and postmortem tracking.
PostgreSQL Backup & Recovery: Tool Selection, Restore Drill & Readiness Framework
Complementary 3-site content set covering PostgreSQL backup and disaster recovery readiness.
PostgreSQL First Restore Drill Runbook
Hands-on runbook to execute your first restore drill and verify dataset consistency.
How to Choose Your PostgreSQL Backup Approach
Tool selection guide for pg_dump, pg_basebackup, pgBackRest, Barman, and WAL-G based on dataset size, RPO/RTO targets, and storage.
From Backup Success to Recovery Readiness: The Restore Drill
Standardizing recovery readiness across engineering teams: maturity tiers, RACI roles, pre/during/post-drill checklists, and audit templates.
