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 ?

Query below returns list of users in current database. To list all the tables of a particular database first, you need to connect to it using the \c or \connect meta-command. From time to time it is very useful that you can generate the DDL commands for existing objects (Tables, Indexes, whole Schema …). IN ACCESS SHARE MODE, so Eg. 3. The STATEMENT field is a key factor that sets pgAudit apart from using Postgres statement logging only. So, the maximum length of schema name can be of 30 characters and you can input 7 to 8 schema names. Is there any way we can automate the Postgres user, databases, and roles management without manually creating roles? Clean, readily usable information in log files which has real business value from the auditor perspective is called an audit trail . 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 ?
