pg_exporter-v1.4.1

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

Highlights:

• Fix pg_subrel_count overcounting when parallel logical replication apply workers are active: deduplicate pg_stat_subscription by subscription ID and name before aggregating subscription relation states
• If a query result omits a configured LABEL column, that collector's scrape now fails atomically instead of emitting an empty label or retaining 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, allowing direct upgrades
• Refresh version and standalone package metadata, add missing-label regression coverage, and validate RPM configuration, artifact names, and compatibility metadata in CI

Upgrade Notes:

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