Hot-standby restore — read-only replica fed entirely from the backup pipeline
Manage hot-standby PostgreSQL instances fed by the backup pipeline.
A standby is a configured PGDATA dir with standby.signal + restore_command pointing at our 'wal fetch' shim. PG starts in recovery mode, applies the restored backup, and continuously pulls new WAL from the repository — without touching the source PG.
v0.1 provisions the data dir; the operator starts PG via systemd or pg_ctl. The Result body emits the recommended invocation.
The state file lives under paths.State()/standbys.json — same back-compat commitment (24-month) as the manifest schema.
-h, --help help for standby
--airgapped airgapped: strict refuse outbound endpoints (LLM providers, sinks, OTLP collectors) outside loopback / RFC1918 / explicit airgap.allowlist. Also enabled by PG_HARDSTORAGE_AIRGAPPED=1 or airgapped: strict in the config file.
-c, --config string path to config file (default: XDG/FHS lookup)
--cpu-profile go tool pprof <path> write a pprof CPU profile to this path for the duration of the command (go tool pprof <path> to analyse). Off when empty.
--mem-profile string write a pprof heap profile to this path at command exit. Off when empty.
--no-color disable ANSI color in text output
--on-error-llm on a structured-error failure, drop into the matching LLM helper skill (auto_on_error trigger). Also enabled by PG_HARDSTORAGE_ON_ERROR_LLM=1.
--otel-endpoint string OpenTelemetry OTLP/HTTP endpoint (e.g. http://otel-collector:4318); empty disables tracing
--otel-stdout also export OpenTelemetry traces to stderr (useful for dev)
-o, --output string output format: text|json|ndjson|yaml|template|csv|markdown|html|tap|junit|pdf (default: text on TTY, json off-TTY)
--profile-port go tool pprof http://127.0.0.1:6060/debug/pprof/profile?seconds=30 if non-zero, expose net/http/pprof on 127.0.0.1:<port> for live profiling of long-running commands (e.g. go tool pprof http://127.0.0.1:6060/debug/pprof/profile?seconds=30). Off when zero.
-q, --quiet suppress non-essential output
--template string Go text/template applied when --output template (or implied if --template is set without --output)
