Обсуждение: DDLs of a Function
Hi Postgres Community, We want to drop a table and recreate it. As we all know, dropping a table even drops the dependent objects like views, MVs, functions. I wanted your help to get the DDL of the (dependent) function before we can drop the table. Once the dropped table is being recreated, this DDL will be helpful to recreate that function. We found a way to get the DDL of the Views and MVs, but not for function! :( Can someone please help ?

Hello Pratik,
There is a open source db client 'dbeaver'
You can use this to get the DDLs for the functions.
Attached is the screenshot for your reference,

You can use "pg_get_functiondef": SELECT pg_get_functiondef('pg_get_functiondef'::regproc); pg_get_functiondef --------------------------------------------------------------- CREATE OR REPLACE FUNCTION pg_catalog.pg_get_functiondef(oid)+ RETURNS text + LANGUAGE internal + STABLE PARALLEL SAFE STRICT + AS $function$pg_get_functiondef$function$ + (1 row) This article contains something about view dependencies: https://www.cybertec-postgresql.com/en/tracking-view-dependencies-in-postgresql/ Yours, Laurenz Albe -- Cybertec | https://www.cybertec-postgresql.com
