Data Definition Language (DDL): How to add an Added Date timestamp to all your tables that don't have them. -- ALTER TABLE stealthis.Person DROP CONSTRAINT Address_fk; ALTER TABLE stealthis.Person ADD CONSTRAINT Address_fk FOREIGN KEY (AddressId), REFERENCES stealthis.Address (Id) MATCH FULL. 2. From time to time it is very useful that you can generate the DDL commands for existing objects (Tables, Indexes, whole Schema …). So many people in PostgreSQL forums and mail lists do not understand why the hell should someone need to get DDL for table directly in PL/pgSQL. Like several of its commercial competitors, one of the more advanced features of PostgreSQL is its ability to perform transactional DDL via its Write-Ahead Log design. Hi,

How do i get DDL of a Table from system catalog ?

Purpose :
1) i need to create an external table on the basis of  another table.
     create table ext_table (like table_name); ------------------> this doesnot work for external tables.
2)  so i need to query catalog to get  definition of the table.
     on the basis of this definition i can create external table .
eg: i am looking for some thing like :

   select * from pg_catalog where table_name=' srikanth_ext_parallel_crt_sms_logs_child_depth_1_d_2008_03_30_daily ' ;

3) once i get the definition of the table , i need to use that definition for creation of external table in a script which will run in cron job daily for data loading.

Can anyone guide/help me in this ?

Now that our new user "mytest" exists you can use ALTER USER to change the permissions granted to the librarian. In our case, we expect at least 10+ users for 10+ applications with multiple roles (read-only, read-write, admin). How do i get DDL of a Table from system catalog .
