Question

First of all, I'm sorry for my bad English.

Hi, I have the following problem:

I have a database in postgres that I need to map, to obtain their entities. All this seems to work well. The problem comes when I want to do my first 'migrations: diff', which for some reason in the migration file deletes all the sequences, which I should not do.

I need to be able to migrate without having to worry about having to erase from the file, the sequence, every time I'm going to make a change in some entity.

I detail my steps, up to the problem:

I use the following version of Symfony 4 :

Symfony 4.2.7

1º php bin/console doctrine:mapping:convert --from-database annotation ./src/Entity

2º php bin/console make:entity --regenerate

3º php bin/console doctrine:migrations:generate

4º When executing this code : php bin/console doctrine:migrations:diff

I get the following in the migration file :
