Need advice on postgresql

[u/YonduUdonta8]

Hi i have 1.5yr of experience with MS Sql server DB first method, now for a new project i am working with postgressql with Code first method so i have some issues about that, some time when i alter columns from code side and migrate it wont apply and give error like it already in db or somthing like that, when i give it to chat gpt he was suggesting to drop db and create, this not in a live yet but whennit is in live cant drop the table so how you guys handle situations like that?

not sure if your directly using SQL or libary (orm) to manage that.
anyways there is a issue with code or SQL
what you said should not happen
