Connecting cakephp 2.0 with PostgreSQL

问题

I am using cakephp 2.0 and a wamp server. I have enabled the pdo of postgres in the php and i tried connecting to Postgres. However it still says that there is an error. My login and password is also double confirmed.

Below is codes for the database.php file:

public $default = array(
  'datasource' => 'Database/Postgres',
  'persistent' => false,
  'host' => 'localhost',
  'port' => '5432',
  'login' => 'postgres',
  'password' => 'password',
  'database' => 'Test',
  'schema' => '',
  'prefix' => '',
  'encoding' => ''
 );

I even tried this:

public $default = array(
    'datasource' => 'Database/Postgres',
    'persistent' => false,
    'host' => 'localhost',
    'port' => '5432',
    'login' => 'postgres',
    'password' => 'password',
    'database' => 'Test',
    'schema' => 'public',
    'prefix' => '',
    'encoding' => ''
  );

My pga_hba.config file is:

 TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# IPv4 local connections:
host    all         all         127.0.0.1/32          md5
# IPv6 local connections:
host    all         all         ::1/128               md5

In the C:\wamp\bin\php\php5.3.9\ext

I have both:

php_pdo_pgsql.dll
php_pdo_sqlite.dll

My config Postgres config file is :

listen_addresses = '*'      # what IP address(es) to listen on;
                    # comma-separated list of addresses;
                    # defaults to 'localhost', '*' = all
                    # (change requires restart)
port = 5432             # (change requires restart)
max_connections = 100           # (change requires restart)
# Note:  Increasing max_connections costs ~400 bytes of shared memory per 
# connection slot, plus lock space (see max_locks_per_transaction).
#superuser_reserved_connections = 3 # (change requires restart)
#unix_socket_directory = ''     # (change requires restart)
#unix_socket_group = ''         # (change requires restart)
#unix_socket_permissions = 0777     # begin with 0 to use octal notation
                    # (change requires restart)
#bonjour_name = ''          # defaults to the computer name
                    # (change requires restart)

I check php info and I still found that that the pgsql was not there. I am using wamp server.

[PostgresSQL]
; Allow or prevent persistent links.
; http://php.net/pgsql.allow-persistent
pgsql.allow_persistent = On

; Detect broken persistent links always with pg_pconnect().
; Auto reset feature requires a little overheads.
; http://php.net/pgsql.auto-reset-persistent
pgsql.auto_reset_persistent = Off

; Maximum number of persistent links.  -1 means no limit.
; http://php.net/pgsql.max-persistent
pgsql.max_persistent = -1

; Maximum number of links (persistent+non persistent).  -1 means no limit.
; http://php.net/pgsql.max-links
pgsql.max_links = -1

; Ignore PostgreSQL backends Notice message or not.
; Notice message logging require a little overheads.
; http://php.net/pgsql.ignore-notice
pgsql.ignore_notice = 0

; Log PostgreSQL backends Noitce message or not.
; Unless pgsql.ignore_notice=0, module cannot log notice message.
; http://php.net/pgsql.log-notice
pgsql.log_notice = 0

I already did this in my php.ini file:

extension=php_pdo_pgsql.dll
extension=php_pdo_sqlite.dll
extension=php_pgsql.dll

回答1:

A shot in the dark: Is the name of the database Test or test? Unquoted identifiers are cast to lower case in PostgreSQL. The manual about that.

Next shot in the dark: You are connecting to localhost. This is not a local connection via Unix domain socket. For this to work the database must be set up to listen to TCP/IP connections. So you need in your postgresql.conf:

listen_addresses = '*'

.. and restart.

Also, your pg_hba.conf settings need to allow the connection. Could be a problem similar to this one.
Start by reading the chapter Connection Settings in the fine manual.

But I am done guessing now. You need to provide the error message.
