Based on your situation, it would make sense I think to disable whatever PostgreSQL you have and start over with a fresh install. We are dealing with completely different applications that have nothing to do with eachother. In reality, PostgreSQL is only needed to serve up data. It makes sense to me, to simplify your life by installing PostgreSQL seperately and treating it as a totally independant application.
The simplest way to go about this, would be to take the following steps.
- Determine if PostgreSQL is currently running
A. If it is, locate it and disable it
B. If it isn't move onto step 2
- Download PostgreSQL 9.2 from PostgreSQL's website
- Install dependancies
- Configure, compile and install postgresql
- Initalize your database and start postgres
- What's next
1. Determine if PostgreSQL is currently running
From the shell, type the following
[root@someserver ~]# netstat -tlpn | grep postmaster
tcp 0 0 0.0.0.0:5432 0.0.0.0:* LISTEN 1119/postmaster
tcp 0 0 :::5432 :::* LISTEN 1119/postmaster
Postmaster on my machine is the PostgreSQL service. It is listening on port 5432 and has a process id of 1119.
Where is it?
Now that we have the process ID we can locate the files being used. lsof is handy because it will show you all the files and sockets a given process is using.
[root@someserver ~]# lsof -p 1119
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
postmaste 1119 postgres cwd DIR 253,3 4096 131093 /var/lib/pgsql/9.1/data
postmaste 1119 postgres rtd DIR 253,0 4096 2 /
postmaste 1119 postgres txt REG 253,4 5205008 27145 /usr/pgsql-9.1/bin/postgres
On my server, it is using /usr/pgsql-9.1/bin/postgres to run the service and the /var/lib/pgsql/9.1/data is the data directory.
From this point you know where its running and what directories its using.
On your server, it looks like its installed in /usr/local/Cellar/postgresql. If you have to start it manually, then you can just leave it alone. When you install PostgreSQL from source, it will install in /usr/local/pgsql by default.
It is only important to be sure that the postgresql currently installed on your system is not using port 5432. This is because two services can not use the same port. If it is, you will need to kill the process and keep it from starting again. Based the contents of your question, it looks like that won't be a problem.
2. Download postgresql
From the shell
[root@someserver ~]# cd ~
[root@someserver ~]# wget http://ftp.postgresql.org/pub/source/v9.2.2/postgresql-9.2.2.tar.gz
[root@someserver ~]# tar -zxvf postgresql-9.2.2.tar.gz
3. Install dependencies
I didn't notice you mentionning what flavor of Linux you were running. You can identify your OS by running cat /etc/issue.
PostgreSQL depends on several libraries.
On CentOS, I would run this to install the libraries I needed
[root@someserver ~]# yum install readline-devel zlib-devel make gcc g++
On Debian, you would use apt-get to install and apt-cache search to locate. I included build-essential because you'll need it to compile postgres.
Something like apt-get install libreadline6 libreadline6-dev build-essential
Not sure about OSX though
4. Configure, Compile and Install PostgreSQL
[root@someserver ~]#
cd postgresql-9.2.2
The --bindir option will put the the postgresql binaries like pg_ctl, initdb, createdb all in the /usr/bin directory. This will be handy for you since you mentionned having trouble finding them.
./configure --bindir=/usr/bin
make
make install
You can check to see if the binaries are available
[root@someserver ~]# psql -V
psql (PostgreSQL) 9.2.2
Once this is done, normally you would need to add the postgres user, but he's already on your system
You do however need to create a data directory and give postgres read/write access to it
[root@someserver ~]# mkdir -p /var/lib/pgsql/data
[root@someserver ~]# chown postgres:postgres -R /var/lib/pgsql/data
[root@someserver ~]# su - postgres
PostgreSQL is installed
You have created a data directory
Now you can initalize your database
5. Initalize and start postgres
initdb -D /var/lib/pgsql/data
This will the cluster and your configuration files such as postgresql.conf, pg_hba.conf which you will need to modify later based on the users that need access, their ip addresses and what ip address and port postgresql will listen on
Now you can start PostgreSQL with the following command :
/usr/local/pgsql/bin/postmaster -D /var/lib/pgsql/data > /var/lib/pgsql/logfile 2>&1 &
When you run netstat -tlpn again, you should see
[root@someserver ~]# netstat -tlpn | grep postmaster
tcp 0 0 127.0.0.1:5432 127.0.0.1:* LISTEN 8721/postmaster
It is only listening to local connections for now, because by defaut that's what postgresql.conf is configured to do.
6. What's next
From here, you would need to configure postgresql.conf and pg_hba.conf appropriately. pg_hba.conf defines who can connect, from where and to what. postgresql.conf is used to configure the entire service, what ip address or addresses it listens on, what port number, maintenance cyles, etc. For your purposes, you will probabaly only be interested in changing this variable
listen_addresses = '*'
You may also want to create an init script in the /etc/init.d directory, so it will start automatically. How you go about that also depends on what flavor of Linux you are running.
If you run into any problems let me know. Since you are probably not using the exact same system, you may run into problems I haven't discussed here.
Best Answer
Just type it into the "Group" field. Besides the listed options you can type a new group name freely.
It's a setting of pgAdmin, completely independent of the database itself and not stored in the database.
The handling is flexible, but renaming a bunch of "servers" can get tedious.
As to your comment: I repeat what I already wrote in my last answer:
But if you follow my instructions over there, you connect to the right database automatically. I suggest, you read the manual about Managing Databases for basic understanding.
