PostgreSql connection for pivot table reports

PostgreSql or protocol-compatible database (like Amazon Redshift) can be used as a data source with SQL-compatible database connector.

Connection String should be a valid connection string for NpgSql driver; for example:

Host=hostName;Port=5432;Database=db;User ID=user;Password=password;
Host Specifies the host name of the machine on which the PostgreSql is running.
Do not use "localhost" or LAN server name; use only public IP address or server's domain name.
Database The PostgreSQL database to connect to.
User ID The username to connect with.
Password The password to connect with.
SSL Mode Specify SSL Mode=Require to force SSL or if your PostgreSql allows only SSL connections.
Trust Server Certificate Specify Trust Server Certificate=True to allow self-signed SSL server certificates.
Server Compatibility Mode Specify Redshift if your configure a connection to Amazon Redshift.

Troubleshooting

Server certificate was not accepted
Add Trust Server Certificate=True to the connection string to disable SSL certificate validation (needed if your server uses self-signed certificate).
ERROR: operator does not exist
Most likely you've specified a filter for column and value is not comparable with the datatype of this column (PostgreSql uses strict typing). Workaround is casting the column to the datatype needed for comparison.
For example, if you got operator does not exist: text > numeric and your filter is some_column < 5 this means that some_column is TEXT type. To fix that go to the cube configuration form, find the dimension with Name "some_column" and add a Parameter to define SQL expression with a cast:
some_column::NUMERIC
