I am trying to access postgresql from a C program running on Win XP. The database server is Linux and I can connect with it using SSH and psql but I have had not success connecting using PQconnectdb. I get the following error:
libintl-8.dll was not found. I’m using Microsoft Visual C++ .NET 2003. That .dll is not on the computer and I don’t know how to get one.
Thanks,

Dave

Nice article.
Note that the listen_addresses must be comma separated as:
listen_addresses=’202.54.1.2, 202.54.1.3′

No more need to use IPTABLES, just type some: « sudo ufw allow 5432 » and you’re done ;)
Many thanks!

Thanks for the doc: it resolved my issue.

There is a small syntax error in your listen_addresses field (step #3): the list should be comma (NOT space) separated.

Hello All,

I have postgre installed via ports and the only config file I have is :
/usr/ports/databases/postgresql82-server/files/patch-src:backend:utils:misc:postgresql.conf.sample

Any idea of what could it be ?

Hello,

In CentOS 2.6.9-89.0.16.plus.c4smp :

Verify /var/lib/pgsql/data/postgresql.conf :

Not only change:

from:
#tcpip_socket = false

to:
tcpip_socket = true

But too:

from:
#port = 5432

to:
port = 5432

In /var/lib/pgsql/data/pg_hba.conf add:

host name_base name_user 0.0.0.0/0 md5

host name_base name_user fixed_ip md5

It is working now as I had to use the below …

By: eddie

eddie — Wed, 29 Apr 2009 10:26:13 +0000

I am still having problems connecting. my pg_hba.conf file is thus
# “local” is for Unix domain socket connections only
local all all * trust
IPv4 local connections:
host all all * trust
# IPv6 local connections:
host all all ::1/128 ident sameuser

my error message is this
psql -h 127.0.0.1 -d template1
psql: FATAL: missing or erroneous pg_hba.conf file
HINT: See server log for details.

what am I doing wrong cause it was working before..

No Need to install PostgreSQL on same server. To connect via php, simply specifiy server IP, username and password. You also need to open port using iptables. Also, remote connection between two servers in the same data center is recommended. If you have a two different data center consider security (which can be overcome using SSL connection between db server and php app server) and latency.

Okay, that’s great for remote access via ssh. My problem is that there is a PostgreSQL Server in one datacenter, and a php based website in another data center. I’m told that you can’t enable PostgreSQL support in PHP w/o actually installing PostgreSQL Server on that machine, but I don’t want PostgreSQL on the webserver, and I have a customer that want’s to use it via his website w/PHP.

This is what I’ve gotten so far from php.net:

In order to enable PostgreSQL support, –with-pgsql[=DIR] is required when you compile PHP. DIR is the PostgreSQL base install directory, defaults to /usr/local/pgsql. If shared object module is available, PostgreSQL module may be loaded using extension directive in php.ini or dl() function.

and from http://us3.php.net/manual/en/pgsql.requirements.php I get:

To use PostgreSQL support, you need PostgreSQL 6.5 or later, PostgreSQL 8.0 or later to enable all PostgreSQL module features.

So my question is, can I, or how can I enable PostgreSQL support in PHP w/o installing the actual database server on that particular machine?

Thanks,

Bradley

Hi all,

Now, i m facing problem in log in to postgresql by webmin interface. Problem is that all a long I used to login postgresql DB by webmin interface and able to login smoothly . But last few days ago , i ‘ve changed the root (super user) password and not able to log in at all . I believe password has been wrong for over 3 times and IP address has been blocked .
Hence , I ‘ve tried to login from different IP address and also the same thing encountering.
I ‘m using Postgresql very 7 + . Kindly pls help me to solve my problem by how to enable such thing back to normal . There is no IP talbes restrictions .

Looking forward to your solutions..

How is this:
1, Listen to the world *
2, Use md5
3, only those database allowed
4, only specific user.
I will try this.
