/**
 * Metric operations for the v-next Postgres observability domain.
 *
 * Implements the full ObservabilityStorage metric surface — write, list,
 * aggregate, breakdown, time series, and percentiles. The OLAP queries
 * lean on standard Postgres aggregates (`SUM`, `AVG`, `percentile_cont`,
 * `FILTER (WHERE …)`) and a portable epoch-floor bucket expression so the
 * adapter works on vanilla Postgres and on a TimescaleDB hypertable
 * without query rewrites.
