Обсуждение: pg_ctl won't start postgres, but postmaster will?!

I have had a lot of problems trying to install the postgres on a second
FreeBSD box. I installed it using the ports install, so that part of the
process went painlessly. however, when I tried to run the .sh script file
that was installed, I get nothing. The script's commands are:

    chmod 600 ${logfile}
    chown pgsql:pgsql ${logfile}
    [ -x ${PGBIN}/pg_ctl ] && {
        su -l pgsql -c \
            "[ -d \${PGDATA} ] && exec ${PREFIX}/bin/pg_ctl start -s -w -l
${logfile}"
        echo -n ' pgsql'

No errors, no messages, nothing. Then I tried to start pg_ctl by hand. I
su'd to pgsql, and typed:

/usr/local/bin/pg_ctl -D /pgdata -l /var/log/pgsql

and nothing, postmaster still doesn't start! If I type:

su -l pgsql -c exec "/usr/local/bin/postmaster -D /pgdata"

I get a "postmaster started successfully" reply, BUT postmaster STILL isn't
running.

The only way I can get postmaster to run is to first su into pgsql, then
type:

/usr/local/bin/postmaster -D /pgdata

Then it starts up fine! None of this makes any sense to me at all. On a side
note, even when postmaster is running, webmin says that postgres isn't
running, even tho I told it where the database is. Just one more thing
that's messed up. Any ideas as to why this isn't working?

You forgot the "start" keyword.  I'm surprised pg_ctl fails to complain...

This command is invalid.  You need to add "start" somewhere.

The message "postmaster started successfully" comes from pg_ctl.  That
would mean pg_ctl is still running by the time you type this.

Please check that what you are writing here corresponds exactly to what
you are typing on the console.

Sorry, forgot to write that. It was in the line. The wierd thing is that I
can type:
/usr/local/bin/pg_ctl -D /pgdata -l /var/log/pgsql start

and it will start, but if I use:

su -l pgsql -c exec "/usr/local/bin/pg_ctl -D /pgdata -l /var/log/pgsql
start"

it doesn't work! And I'm still confused as to why the script doesn't work.

Sorry about that. I should have just copied and pasted. Thanks for pointing
out my error!

Terse answer: Do not use quotes in your exec statement.
