Hrm... That does not work either:
# select use_two_tables('tablename');
ERROR: function use_two_tables("unknown") does not exist
HINT: No function matches the given name and argument types. You may need
to add explicit type casts.
# select use_two_tables('tablename'::text);
ERROR: function use_two_tables(text) does not exist

I am not really sure... just learning this, but I believe the parameter
type is tablename, right?
>>CREATE TABLE tablename( ...
>>CREATE or REPLACE FUNCTION use_two_tables(tablename) RETURNS text AS '
>>...
Do I need to cast the string to something?
# \df use_two*
List of functions
Result data type | Schema | Name | Argument data types
------------------+--------+----------------+---------------------
text | lee | use_two_tables | tablename
(1 row)
# select use_two_tables('tablename'::tablename);
ERROR: cannot cast type "unknown" to tablename
# select use_two_tables(tablename::tablename);
ERROR: column "tablename" does not exist
Thanks for your help.
