Postgres: database uptime

  • Formatted Uptime To display uptime in a more readable format (e.g., truncated to seconds):

SELECT date_trunc('second', current_timestamp - pg_postmaster_start_time()) AS uptime;



You can calculate the server uptime by querying the pg_postmaster_start_time() function, which returns the server's start time.

  • Basic Query To get the uptime directly:

SELECT current_timestamp - pg_postmaster_start_time() AS uptime;

My name is Jagadeesh and I will be assisting you with this issue.   I understand that WAL logs are expanding to over 1.5TB and you want to know what is causing WAL logs to grow and you want to reduce it. Please confirm if ...
