Shared links are typically also public database links. In a shared server configuration, shared database links can keep the number of connections into the remote database from becoming too large. Make sure your is set properly before you run the command and the schema is visible to all users who have to work with it.Specify SHARED to create a database link that can be shared by multiple sessions using a single network connection from the source database to the target database. With PostgreSQL 9.1 or later, installation of additional modules has been simplified.Д¬an be installed with: CREATE EXTENSION dblink Installs into your default schema ( public by default). This is the line is type: SELECT dblink_connect_u('host=x.x.x.x dbname=mydb user=root port=5432') IP Address is correct and Postgres is running on the remote server.

I keep having a could not establish connection. Does anybody have an idea? Do we have to 'activate' dblinks or do something before using them? Is there something to do on the remote database we are going to query? Do we have to activate dblink too? You might need to add explicit type casts. I am used to Oracle and to create a dblink in my schema and then access to a remote database like this: is there anyway do to the same with PostgreSQL? Right now I am using dblink like this: SELECT logindate FROM dblink('host= user=toto password=isok dbname=totofamily', 'SELECT logindate FROM loginlog') When I execute this command I get the following error: HINT: No function matches the given name and argument types.
