[pgsql.general] Problem connecting PostgreSQL 8.2 to Rails 1.2

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello people,

I just installed PostgreSQL on my Mac.
I used the package available here:
http://www.entropy.ch/software/macosx/postgresql/

Here is a screendump of initdb...

$
$
$
$
$ /usr/local/bin/initdb -E UTF8 -D /usr/local/pgsql/data
The files belonging to this database system will be owned by user
"maco".
This user must also own the server process.

The database cluster will be initialized with locale C.

creating subdirectories ... ok

selecting default shared_buffers/max_fsm_pages ... 2400kB/20000

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:

/usr/local/bin/postgres -D /usr/local/pgsql/data
or
/usr/local/bin/pg_ctl -D /usr/local/pgsql/data -l logfile start
$
$
$

I started the server:

$
$
$
$ pg_ctl start
server starting

I created a database:
$
$
$
$ createdb e10d
CREATE DATABASE
$
$
$


I created a table:

$
$
$
$ psql --help

This is psql 8.2.3, the PostgreSQL interactive terminal.

Usage:
psql [OPTIONS]... [DBNAME [USERNAME]]

General options:
-d DBNAME specify database name to connect to (default: "maco")
-c COMMAND run only single command (SQL or internal) and exit
-f FILENAME execute commands from file, then exit
-1 ("one") execute command file as a single transaction
-l list available databases, then exit
-v NAME=VALUE set psql variable NAME to VALUE
-X do not read startup file (~/.psqlrc)
--help show this help, then exit
--version output version information, then exit

Input and output options:
-a echo all input from script
-e echo commands sent to server
-E display queries that internal commands generate
-q run quietly (no messages, only query output)
-o FILENAME send query results to file (or |pipe)
-n disable enhanced command line editing (readline)
-s single-step mode (confirm each query)
-S single-line mode (end of line terminates SQL command)
-L FILENAME send session log to file

Output format options:
-A unaligned table output mode (-P format=unaligned)
-H HTML table output mode (-P format=html)
-t print rows only (-P tuples_only)
-T TEXT set HTML table tag attributes (width, border) (-P tableattr=)
-x turn on expanded table output (-P expanded)
-P VAR[=ARG] set printing option VAR to ARG (see \pset command)
-F STRING set field separator (default: "|") (-P fieldsep=)
-R STRING set record separator (default: newline) (-P recordsep=)

Connection options:
-h HOSTNAME database server host or socket directory (default: "local
socket")
-p PORT database server port (default: "5432")
-U NAME database user name (default: "maco")
-W prompt for password (should happen automatically)

For more information, type "\?" (for internal commands) or "\help"
(for SQL commands) from within psql, or consult the psql section in
the PostgreSQL documentation.

$
$
$ psql -d e10d
Welcome to psql 8.2.3, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help with psql commands
\g or terminate with semicolon to execute query
\q to quit

e10d=# create table dropme(n integer);
CREATE TABLE
e10d=#
e10d=#
e10d=# drop table dropme;
DROP TABLE
e10d=#
e10d=#
e10d=#


Next, I checked my gems to make sure I have the PostgreSQL adaptor:

$
$
$
$ gem list | grep -i postg
postgres-pr (0.4.0)
A pure Ruby interface to the PostgreSQL (>= 7.4) database
$
$
$
$

Next I created my database.yml


$
$
$
$ ll

$

$
$
$ cat config/database.yml


development:
encoding: unicode
adapter: postgresql
database: e10d


production:
encoding: unicode
adapter: postgresql
database: e10p

$
$
$


I tried rake...

$
$
$
$ rake db:migrate
(in /pt/webprops/edgar411/e10)
FATAL: no PostgreSQL user name specified in startup packet
rake aborted!
FATAL C28000 Mno PostgreSQL user name specified in startup packet
Fpostmaster.c L1525 RProcessStartupPacket

(See full trace by running task with --trace)
$
$
$


I checked my
/usr/local/pgsql/data/pg_hba.conf
file...

$
$
$
$ grep -v '#' /usr/local/pgsql/data/pg_hba.conf|sort -u

host all all 127.0.0.1/32 trust
host all all ::1/128 trust
local all all trust
$
$
$

It looks fine to me.

So,
Here is the error:
FATAL: no PostgreSQL user name specified in startup packet

Here is some info about my rails setup:

$
$
$
$ script/about
FATAL: no PostgreSQL user name specified in startup packet

Do any of you Rails-PostgreSQL people have any clues about the
problem?

Anyone out there running Rails 1.2.3 with PostgreSQL 8.2 ??

What does your database.yml look like?
How about your
/usr/local/pgsql/data/pg_hba.conf
file?
