v0.52.0

• OpenTelemetry integration: Allow exporting EXPLAIN plans as trace spans
  • This is an experimental feature that allows configuring the collector
    to send an OpenTelemetry tracing span for each processed EXPLAIN plan
    with an associated traceparent query tag (e.g. set by sqlcommenter)
    to the configured OpenTelemetry endpoint
  • To configure the OTLP protocol endpoint, set the new config setting
    otel_exporter_otlp_endpoint / OTEL_EXPORTER_OTLP_ENDPOINT, with a
    endpoint string like "http://localhost:4318". You can also optionally
    set the otel_exporter_otlp_headers / OTEL_EXPORTER_OTLP_HEADERS
    variable to add authentication details used by hosted tracing providers
    like Honeycomb and New Relic
• Relax locking requirements for collecting table stats
  • This avoids skipped statistics due to page or tuple level locks,
    which do not conflict with pg_relation_size as run by the collector.
• Activity snapshots: Normalize queries for filter_query_sample = normalize
  • This matches the existing behavior when filter_query_sample is set
    to all, which is to run the normalization function on pg_stat_activity
    query texts, making sure all parameter values are replaced with $n
    parameter references
• Self-managed servers: Add test run notice when system stats are skipped
• Docker log tail: Re-order args to also support podman aliased as docker
