PostgresSQL Setup error

Please advise if assistance can be provided?

Possibly. That error will cause an error message in the PostgreSQL
server log. Ask your DBA to find that error message and tell you
what it says.

Usually, the message means that you provided the wrong password.

To figure out what is going on, one would have to know how exactly
you are trying to connect (the connect string, the data source
definition) and what is in the database server's "pg_hba.conf".

Hi Team,

Hope this email finds you well,

Apologies as I am unaware if this is the correct mailing address.

I would however like to inquire about an issue currently being
experienced with Postgres with one of our external clients.

When doing the setup and following the steps accordingly with regards to
adding the details for PostgreSQL Unicode ODBC Driver and testing, I run
into an error where it states the below.

*note - I was provided with the username and password .

"psql: FATAL: password authentication failed"

Was that the complete message?

Not something like:

psql: error: connection to server at "localhost" (127.0.0.1), port 5482
failed: FATAL: password authentication failed for user "aklaver"

Also provide:

1) Postgres version.

2) Client version.

Please advise if assistance can be provided?

Kind Regards

Jordan Adams

Hi,

There could be many reasons , sharing most common ones:

1.
Typo errors ie case sensitive
2.
Password change errors
3.
Incorrect username ,database name , port number
4.
Configuration issues in hba file
5.
Privilege issue
6.
Server Not Restarted/Reloaded or full restart has not taken place for the server

Sharing the psql command for ready reference

psql -h <your_server_ip_or_hostname> -p <your_port> -U <your_username> -d <your_database_name>
