ERROR: copyObject: don't know how to copy 611 - Mailing list pgsql-sql

I get the error ERROR:  copyObject: don't know how to copy 611
when I try to run the following procedure. The create table is causing
the problem.


CREATE FUNCTION "my_func" (int8) RETURNS int8 AS 'declare  v_my_var ALIAS FOR $1;begin  create table my_table(my_id
int);end;
' LANGUAGE 'plpgsql';


Can anybody explain this?

Thanks in advance,

shane
