How to remove readonly in Postgresql?

Question

PostgreSQL

Made a duplicate table using the

CREATE TABLE table_name AS (SELECT * FROM table_name2) command;

And now I can’t edit, it costs readonly, nothing helps.

Answer 1

Postgresql does not prevent you from editing. Since you were able to create a table, it means that the database is not in read only mode. Write an appropriate update and execute.
But your GUI client most likely does not like the lack of a primary key.
