勺到PostgreSQL的连接问题

Question

Error message is thrown while connecting to database from Spoon.

1. Selected the View option that appears in the upper-left corner of the screen, right-clicked on the Database connections option, and selected New.
2. Under Connection Type, selected the postgresql database engine.

3. Filled in the Settings options and gave the connection a name by typing it in the Connection Name. All the credentials entered are valid but still I get the below error message:

   Error connecting to database [XXX-XXX-XXX-XXX ] : org.pentaho.di.core.exception.KettleDatabaseException: Error occurred while trying to connect to the database

   Error connecting to database: (using class org.postgresql.Driver) The connection attempt failed.

   Hostname : XXX-XXX-XXX Port : 1111 Database name : XXX_XXX_XX

Please suggest me how do I fix this issue

Answer 1

Ok first of all check this:

• Server is up and running? (Postgres)
• Why port is 1111 instead of 5432
• Can you connect with pgadmin?

I think is a configuration problem
