Question about postmaster processes

От
"Chris Williams"
Дата:
Since I have upgraded to postgres 6.4, when I do a "ps -ef | grep post", I get a list of postmaster
processes.  With 6.3.2 of postgres, I would have one postmaster process and many different posgres
processes.  Is this normal 6.4?  All I do is start the postmaster process with the -i option.
Any help would be great

We no longer exec() new postgres backends, but just fork the
postmaster.  Faster, but your platform doesn't seem to support 'ps'
args changes that we have made in the backend.  What platform are
you using?

To find the postmaster, just get the parent of all the postmaster-named
processes.

I observed the same situation with: SGI Origin 2000 and IRIX 6.5.
