v1.2.1 updates the build toolchain, standardizes configuration formatting, and adds configuration consistency tests. Collector behavior is unchanged.
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
