I had recently the necessity of detect a node fail over,
and the only way I can do it with a SQL connection is asking
the engine uptime. Of course I can do it with PS but
now that windows version is out I believe a platform
indipendent way is required. Any objection to add it ?
That sounds like a cool idea to me, although I would suggest a function
pg_uptime() that returns an interval or something.
However, adding a new function requires a re-initdb, so it's quite
unlikely this will be in for 8.0.
Is the uptime kept internally anywhere? Or even the start time?
We do this at the start of ServerLoop():
gettimeofday(&earlier, &tz);
and that value isn't changed, AFAICT. However, I'm not sure why an uptime
is all that useful?
Bragging rights? :)
