1. create db by using postgres manager Lite's create db wizard

db name new_db / host : lost host/port: 5432/login: postgres
when I tried to connect to this db I got FATAL error, ¡°database new_db doesn¡¯t exist."


The above suggest that you haven't created your database (new_db) on the postgres server.

---

2. Then I registered new host on port 5433, tried to connect. I got follwing error, ¡°error connection to server, is the server running on host 127.0.0.1, and allow TCP/IP connection on port 5433?¡±

The above error may be due to not setting up your pg_hba.conf correctly to accept TCP/IP connection from your PC. Or it there could be a firewall issue.

To create a database, you can login to your postgres server as Postgres (or whatever the owner of Postgres is) and issue:

createdb your_db_name ;

You may want to check the PostgreSQL docs on creating a database.

Subject: [ADMIN] db connection and script execution error


Dear pgsql-admin members:

I am new to PostgresSql and run into some problems after I installed Posgressql 8.0 and PostgresSql manager 3 Lite. Your advises will be appreciated

I. can't make connection to database
II. can't run a script which will created a database.

I. can't make connection to database

1. create db by using postgres manager Lite's create db wizard

db name new_db / host : lost host/port: 5432/login: postgres
when I tried to connect to this db I got FATAL error, ¡°database new_db doesn¡¯t exist."

2. Then I registered new host on port 5433, tried to connect. I got follwing error, ¡°error connection to server, is the server running on host 127.0.0.1, and allow TCP/IP connection on port 5433?¡±

I checked pgadmin menu If this message appears, there are two possible reasons for this:
a)either the server isn't running at all. Simply start it.

b)The other non-trivial cause for this message is that the server isn't configured to accept TCP/IP requests on the address shown.

Modification done: modified postgressql.conf set listen_addresses='*'
Do I need to set port = 5432, t hen add port 5433 as well? I still got same error message


II. can't run a script which will created a database.

1. run script in EMS postgres manager Lite
run command create database booktown;
¡¤ Error: "ERROR: source database "template1" is being accessed by other users"

2. Run script in pgadmin
Create Database "booktown";
\connect booktown postgres
ERROR: syntax error at or near "\" at character 146

Please give me some advise, I am kind of struck here. I need information on how to create and connect to a database

Where I can find error log message in postgres.org web site which can help me trouble shoot the error message i got.

Sounds like you created a database named something like:

MyDatabase

and are now referencing it as

mydatabase.

Make sure that whatever you call it in the creation wizard you call it
that later. and you can save yourself a lot of little headaches by just
naming everything, everywhere in lower case.

Note that you also have to edit postgresql.conf to get a database to
answer sometimes as well.
