Message-ID: <E1w5HFz-001LaF-1O@gemulon.postgresql.org> (raw)
pg_createsubscriber: Add -l/--logdir option to redirect output to files.
This commit introduces a -l (or --logdir) argument to pg_createsubscriber,
allowing users to specify a directory for log files.
When enabled, a timestamped subdirectory is created within the specified
log directory, containing:
pg_createsubscriber_server.log: Captures logs from the standby server
during its start/stop cycles.
pg_createsubscriber_internal.log: Captures the tool's own internal
diagnostic and progress messages.
This ensures that transient server and utility messages are preserved for
troubleshooting after the subscriber creation process completes or errored
out.
