PL/PGSQL Debugger is supported for PostgreSQL 8.3 or above. The language of the function must be "plpgsql" and you need to install the pldbgapi extension in your database before using the PL/PGSQL Debugger.
PostgreSQL 8.3 to 9.0
You can follow the steps in PostgreSQL Installation Notes (the pl/pgsql Debugger section) which is available in your PostgreSQL server installation folder (e.g. C:\Program Files\PostgreSQL\8.3\doc\installation-notes.html).
