SELECT a.attname
FROM pg_class c, pg_attribute a
WHERE c.relname = '<your-table-name>' AND a.attnum > 0 AND a.attrelid = c.oid
ORDER BY a.attnum ;
gives you the field names of <your-table-name>.
If you start a psql session with the -E option, you can see how
\d <your-table-name> is sql-generated.
If you are asking for support how to write this pgsql function
(table name parameter, query, etc.), then refer to the documentation
or send another request.
