Setting Up Postgresql
Was mucking around with postgresql again, given that I’ve decided to start everything at right footing, rather than to stick with mysql, which is what I’m more used to, for various reasons I’ve remembered from my database lectures in the past.
Installation’s a little bit different from mysql, but with a bit of Googling, there are some pretty good instructions out there that makes things clearer. Subsequently after installation, there may be two error messages to take note of, which you may encounter after the install process:
psql: FATAL: user "vincent" does not exist
If you’re not running as user
'postgres', this error indicates that
the user (in my case
'vincent') does not exist in the database. Upon
installation, postgres only allow the user
'postgres' to access the
database by default, so it’s necessary have the right user profile to
make configuration changes. This is done by invoking
for some users) into
'postgres' and invoke the
% createuser Enter name of user to add: vincent Shall the new user be allowed to create databases? (y/n) y Shall the new user be allowed to create more new users? (y/n) y
The rights allow users to create databases, and to add new users to the
database, which on a standalone machine that I have, it’s probably ok to
'y' for both.
You’re not done with the process yet if you haven’t created your
database for access, and if you executed
'psql' again, the following
error props up:
psql: FATAL: database "vincent" does not exist
This is relatively easy to fix. Since you’ve already have database
creation access, just by issuing
'createdb' will initialize your
database for use.
% createdb CREATE DATABASE
Time to start creating and populating tables from here!
