Обсуждение: Postgres startup

Hello,

We are using version 7.0, and I have noticed that quite often,
postgres fails to start(as much as 50%).  When it does start
everything seems fine.  Any ideas as to why this is occuring.

All installation is done from the downloaded rpms, so nothing
is custom.

Thanks

Jim

    Don't you have any logs from failed attempts to start?

    It is distribution-dependent, if you've got your packages from the OS
distribution.

I've modified the PostgreSQL startup file to include this:

if [ -x /tmp/.s.PGSQL.* ]
    then
    rm /tmp/.s.PGSQL.*
fi

This is for a FreeBSD install, so something may be different, though I
doubt it.

If Postgres wasn't shut down gracefully, this will remove its old lockfile.
(I've noticed Postgres doesn't log anything about this, it just refuses to
start). Also, clearing /tmp on startup might also do the trick. So, if
you were having trouble with Postgres not coming up after system crashes,
this might be the problem. (This is what fixed it for me).
