Thanks q so much for that sharing , but i have a question , after i follow you script i’ve successfully copied new db by run the follow script:

create database newdb with template chatdevdb owner chat_real;
But after I check the tablespace of both databases (chatdevdb(old),newdb(new)) they are stored in the same tablespace and the data size is different:

List of databases
Name | Owner | Encoding | Collate | Ctype | Access privileges | Size | Tablespace | Description
———–+———–+———-+————+————+——————-+———+————–+——————————————–
a | pgdba | UTF8 | ko_KR.utf8 | ko_KR.utf8 | | 6803 kB | pg_default |
chatdevdb | chat_real | UTF8 | ko_KR.utf8 | ko_KR.utf8 | | 50 MB | tbs_chat_dat |
newdb | chat_real | UTF8 | ko_KR.utf8 | ko_KR.utf8 | | 7731 kB | tbs_chat_dat |

the chatdevdb(old) is 50M and newdb(new) is 7731kB, pls you explain me why?

Thanks q in advance
