Every migration:generate creates DROP/CREATES constraints and keys

[amilkarSingular]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

When I run migration:generate and migration:run and the first time it generate me the CREATE TABLE and index fine and migrations runs perfect, but at the second time (without change anything in tables), it generate me ALTER TABLE DROP and ADD constraints queries of all entities again, like if synchronize was turn on.

Minimum reproduction code

https://github.com

Steps to reproduce

npm run migration:generate
npm run migration:run

Expected behavior

At the second time without any changes in entities, the output of migration:generate should be empty in up() and down() functions.

At the next time with some changes in entities, the output should be SQL queries with only the changes I made, not changes I made + DROP/CREATES constraints.

Even I run it it throw me error saying "some constraints already exists"
