Обсуждение: Can't login/createdb
This is the stupidest thing ever and I'm sure I'm missing something simple, but here goes: I installed postgres and started it up as the post-installation-notes file says to do. It starts up just fine, but I cannot log into the interactive monitor, nor can I create any databases, even as root. I checked the pg_hba.conf file and it is set to let all local users log in. Whenver I type: psql to try and log in, I get FATAL 1: Database "username" does not exist in the system catalog. I've used pgsql before, but never installed it, so I assume I missed something stupid, but looking back through the docs I'm still missing it. Can anyone help me? Thanks, Joe

Thanks, What you need to do: 1) Become user 'postgres' (or whatever the postmaster is running as)--this is the Postgres superuser. 2) Run "createuser" to create other allowed users. 3) Run "createdb" to create other databases. 4) Use "psql <dbname>" to connect to them.

by default psql conects to a database by the same name as the user. So you have two problems here. There's no user or database named joe (assuming that's your username on your system) On a fresh install there's only one user, postgres, and only one database to login, template1. psql -U postgres template1 This should. Once connected, create an user for you (and any other you might need). You might want ot give it permissions to create DB's and users. dado.

Alright, I've got that taken care of now. Thanks to everyone who responded. Next dumb question - I need to be able to connect to postgres from PHP - I know that I need to start it up with the '-i' option, but I need to make sure it starts up with that option when the machine reboots. I found the 010.pgsql.sh file and it says to edit $PG_DATA/postgresql.conf - so I went to my data dir and uncommented the line that said 'tcpip_socket = false' and changed it to true. When trying to connect from PHP, I get an error stating: Warning: Unable to connect to PostgreSQL server: pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally before or while processing the request. I'm sure that, once again, I'm missing something simple (Yes, I did stop and restart the postmaster :) Thanks, By the way, this is FreeBSD 4.3 with PHP 4.0.6 Joe wsheldah@lexmark.com wrote: > > Use `su -` to be come root, then `su - postgres` to become the postgres > superuser.

Are you sure? If PHP uses libpq than it should be able to use Unix domain sockets (on the same machine of course). > I found the 010.pgsql.sh file and it says to edit > $PG_DATA/postgresql.conf - so I went to my data dir and uncommented the > line that said 'tcpip_socket = false' and changed it to true.

This probably means the backend > terminated abnormally before or while processing the request. Well, this is either a backend crash (bad) or possibly an authentication failure. What do your logs say? Are there any core files in $PGDATA? -Doug -- Let us cross over the river, and rest under the shade of the trees. --T. J. Jackson, 1863
