What do you not understand about relation "mytable" does not exist ? It does mean that you will have to create the table in postgresql yourself, before trying to import data.
There is a drop option in a table, there import the .txt file in the drop-down options with corresponding column name. Later refresh the table, then view it. Walah, you got table exactly as your .txt file. Thank You.
