How to import data from MDB or pipe delimited file into PostgreSQL

What is the best way to import into a PostgreSQL database data from a
Microsoft Access database?

Should I export the data to a pipe or comma delimited file and then import?
*But how can I do that* ?

With mSQL it is easy, it has already a builtin function where you specify
the name of the text file you are importing, the database and table to input
the data, which character should be treated as a separator (comma, pipe,
etc.).

TIA,
