Release Notes

The latest stable version of pg_exporter is v1.4.1

v1.4.1

v1.4.1 is a maintenance release focused on metric accuracy and RPM upgrade compatibility.

Highlights:

• Fix pg_subrel_count overcounting with parallel logical replication apply workers. Deduplicate pg_stat_subscription by subscription ID and name before aggregating subscription relation states.
• If a query result omits a configured LABEL column, fail the entire collector scrape. Do not emit an empty label or keep stale results. Other non-fatal collectors continue normally.
• Rename the official RPM package and artifact prefix from pg_exporter to pg-exporter. The new package provides and obsoletes the legacy name to support direct upgrades.
• Update version and standalone package metadata. Add regression tests for missing labels. Validate RPM configuration, artifact names, and compatibility metadata in CI.

Upgrade Notes:

• Custom collector SQL must return every LABEL column. The result schema must be complete even if the query returns zero rows.
• If automation matches GitHub RPM file names directly, change pg_exporter-*.rpm to pg-exporter-*.rpm.

v1.4.0

v1.4.0 adds Snapshot Histogram metrics and the pg_xact_age transaction age collector. It also improves HTTP routing, packaging, and the build toolchain.

New Features:

• Add the HISTOGRAM column type. It aggregates SQL snapshots by label group into classic Prometheus histograms with _bucket / _count / _sum series. Configuration loading validates finite bucket bounds in strictly increasing order and appends +Inf automatically. The le label is reserved. Hot reload is supported.
• Add the pg_xact_age collector. It returns open transaction age (pg_xact_age_seconds) and idle-in-transaction age (pg_xact_age_idle_seconds) as histograms. It collects cluster-level data from client backends only, with a 10s TTL.
• Increase the default bundle from 57 to 58 definition files. Assign pg_xact_age to slot 0450. Renumber pg_lock / pg_lock_stat / pg_query to 0460 / 0470 / 0480 without content changes.

Fixes & Improvements:

• Register HTTP routes in a private ServeMux instead of the global DefaultServeMux. This prevents accidental exposure of endpoints from third-party libraries.
• Validate --web.telemetry-path at startup. Reject empty paths, paths without a leading /, paths with ? # { }, and conflicts with built-in endpoints. Also reject non-canonical paths such as //metrics, which cannot match requests. Each failure returns a clear error immediately.
• Escape the telemetry path in the landing page HTML.
• Close the primary connection pool if the --fail-fast pre-check fails.
• Fix RPM / DEB packaging (#105). Set the prometheus user’s HOME to /var/lib/prometheus, where libpq looks for ~/.pgpass. Add /postgres to the packaged default URL. This prevents libpq from using a database named after the OS user.
• Use the v version prefix consistently. Official release binaries report v1.4.0 in --version, /version, and pg_exporter_build_info{version=...}. GoReleaser artifacts previously reported 1.3.0 without the prefix. Artifact file names, package versions, and Docker image tag conventions do not change.
• Apply the same value conversion rules to histograms and scalar columns. Exclude timestamps and booleans from scale.
• Correct GoReleaser package metadata to show support for PostgreSQL 9.x - 19+ and pgBouncer 1.8 - 1.25+.
• Restore GOPROXY / GOSUMDB build-argument passthrough in make docker.

Engineering & Build:

• Update the build toolchain to Go 1.26.5, exporter-toolkit v0.17.1, and prometheus/common v0.70.0.
• Add regular CI checks for module tidy, generated configuration, race tests, and six-platform cross-builds. The make conf output must match config/*.yml.
• Remove the docker/ scripts and make docker-release. Use GoReleaser to build multi-architecture release images.
• Remove assumptions about specific collectors from configuration coverage tests. This makes smaller custom bundles easier to maintain.

Upgrade Notes:

• A non-canonical telemetry path, such as //metrics, now prevents startup. Previously, the process started but the metrics endpoint was unreachable.
• Update automation that parses the version label of pg_exporter_build_info or the --version output to accept the v prefix.
• If any collector uses HISTOGRAM, do not use le as a constant label.

v1.3.0

v1.3.0 adds PostgreSQL 19 support. It also updates the default collectors, build toolchain, and configuration coverage tests.

Highlights:

• Default support range extended from PostgreSQL 10-18+ to 10-19+
• Default config bundle includes 57 config/*.yml definition files
• Build dependencies updated to Go 1.26.4, lib/pq v1.12.3, Prometheus client v1.23.2, and exporter-toolkit v0.16.0
• pg_recovery_state: collect pg_stat_recovery on recovery nodes, exposing promotion trigger status, replay LSN, timeline, recovery transaction time, and pause state
• pg_lock_stat: collect PG19 pg_stat_lock, exposing waits, wait time, and fast-path overflow counts by locktype
• pg_vacuum_score: collect the current-database summary from pg_stat_autovacuum_scores, exposing max autovacuum score and candidate table count
• pg_wal_19: expose wal_fpi_bytes on PG19 as pg_wal_fpi_bytes
• pg_sub_19: adapt sequence sync and logical replication conflict stats from pg_stat_subscription_stats, while keeping sync_error_count for legacy dashboards
• pg_recv: recognize the PG13+ WAL receiver connecting state on PG19
• pg_slot: recognize the PG19 replication slot invalidation reason idle_timeout
• pg_db_confl: switch to an explicit column list to avoid accidentally exporting future view columns
• pg_backup, pg_vacuuming, and pg_clustering continue reusing stable existing branches instead of changing the metric surface for low-value PG19 fields

v1.2.1

v1.2.1 is a maintenance release for release engineering, configuration package consistency, documentation, and metadata. It has no changes to collector or runtime behavior.

Highlights

• Refresh the build toolchain: bump both release workflows and Docker build images to Go 1.26.1
• Standardize config style: switch inline description values in both current and legacy configs to double-quoted form, and regenerate merged pg_exporter.yml / legacy/pg_exporter.yml
• Add config consistency tests: verify split and merged configs remain equivalent, and check inline metric description style to reduce configuration drift
• Refresh packaging metadata: update RPM / DEB support descriptions to PostgreSQL 9.x - 18+ and pgBouncer 1.8 - 1.25+, and refresh Pigsty documentation links

https://github.com/pgsty/pg_exporter/releases/tag/v1.2.1

v1.2.0

v1.2.0 improves stability and compatibility for startup, hot reload, health probes, configuration validation, and legacy support.

New Features:

• Improve hot reload. Support platform-specific signals (SIGHUP / SIGUSR1) and improve POST /reload to update configuration and query plans without a restart.
• Use non-blocking startup. HTTP endpoints start even if the target precheck fails. This improves recovery and monitoring integration.
• Add a legacy configuration bundle for PostgreSQL 9.1-9.6. Use legacy/ and the make conf9 target to configure monitoring for EOL versions.
• Use cached health snapshots with periodic probes. This improves consistency for role-based health endpoints and reloads.
• Add go test and go vet to release workflows. Update the build toolchain to Go 1.26.0.

Bug Fixes:

• Fix configuration parsing cases. Reject malformed metric entries, return explicit errors if a configuration directory has no valid YAML, and improve runtime fallbacks.
• Fix CLI boolean parsing for arguments such as --flag=false.
• Fix /explain output with corrected content types and safer template rendering.
• Improve predicate queries and PG URL handling. Improve BOOL/BOOLEAN support, row resource handling, and dbname query-parameter parsing and redaction.
• Close connections asynchronously when auto-discovery removes a target.
• Fix metric and label validation. Check constant-label conflicts, scaled default values, and Prometheus naming rules.

• pg_table: replace LATERAL subqueries with JOIN to improve performance. Change tuples and frozenxid from COUNTER to GAUGE. Increase the timeout from 1s to 2s.
• pg_vacuuming: add a PG17 branch with indexes_total, indexes_processed, and dead_tuple_bytes to track index vacuum progress.
• pg_query: increase the timeout from 1s to 2s for high-load conditions.
• pg_io: correct the reuses description from “in reused” to “is reused”.
• pg_checkpointer: correct the pg_checkpointer_10 description from “9.4+” to “9.4-17”.
• pg_db_confl: correct the pg_db_confl_15 description from “9.1 - 16” to “9.1 - 15”.
• Correct format alignment for pg_db, pg_indexing, pg_clustering, and pg_backup.
