Why no createuser?

I'm not sure what might be different at your end, but (taking into account the information you've provided about your config files) I've just tried to repeat your test (using a "plain" TC 3.7.1 system freshly started from CD-ROM):

Code: [Select]

tc@box:~$ tce-load -wi postgresql > /dev/null 2>&1
tc@box:~$ export PGDATA=/tmp/test_pg
tc@box:~$ pg_ctl init
The files belonging to this database system will be owned by user "tc".
This user must also own the server process.

The database cluster will be initialized with locale C.
The default database encoding has accordingly been set to SQL_ASCII.
The default text search configuration will be set to "english".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the -A option the next time you run initdb.

Success. You can now start the database server using:

    /tmp/tcloop/postgresql/usr/local/bin/postgres -D /tmp/test_pg
or
    /tmp/tcloop/postgresql/usr/local/bin/pg_ctl -D /tmp/test_pg -l logfile start

As you can see I was able to connect to the (empty) DB. Please note that I had to apply minor tweaks to '${PGDATA}/postgresql.conf', plus my PostgreSQL skills are now a bit rusty so I'm not sure whether these were all the right steps.

Maybe you could document your steps more precisely so that others are able to re-create the situation you are facing.
