Due to permission issues with creating a temporary folder, the two custom tests from PostgreSQL documentation failed as they could not write their results to the temp log file. The issue was resolved by changing the owner of the temporary folder while creating it.
While looking for the issue, the varDump command was commented out as it was not needed and not even found. Also, two tests taken from the documentation were edited; therefore, the slight changes which were made to them to work in our scenario can be highlighted.
