Can't `sync` tables that has columns with `#[sea_orm(unique)]`

[Legend-Master]

Description

When using entity first workflow, I can no longer use sync if one of the column in the table is marked #[sea_orm(unique)] after upgrading to sea-orm-2.0.0-rc.34, it tries to drop the index for some reason

Looking at the recent changes, I believe these commits might be related

From debugging, it seems like we no longer push unique columns to EntitySchemaInfo::indexes so the diff code will now tries to remove the index

sea-orm/src/schema/builder.rs

Lines 390 to 412 in e36eea4

	if let Some(existing_table) = existing_table {
	// find all unique keys from existing table
	// if it no longer exist in new schema, drop it
	for existing_index in existing_table.get_indexes() {
	if existing_index.is_unique_key() {
	let mut has_index = false;
	for stmt in self.indexes.iter() {
	if existing_index.get_index_spec().get_column_names()
	== stmt.get_index_spec().get_column_names()
	{
	has_index = true;
	break;
	}
	}
	if !has_index {
	if let Some(drop_existing) = existing_index.get_index_spec().get_name() {
	db.execute(sea_query::Index::drop().name(drop_existing))
	.await?;
	}
	}
	}
	}
	}

I have only tested with Postgresql but I assume it would be the same for the other backends

Steps to Reproduce

test.rs

use sea_orm::entity::prelude::*;

#[sea_orm::model]
#[derive(Clone, Debug, PartialEq, Eq, DeriveEntityModel)]
#[sea_orm(table_name = "test_table")]
pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i32,
    #[sea_orm(unique)]
    pub name: String,
}

impl ActiveModelBehavior for ActiveModel {}

db.get_schema_builder()
    .register(test::Entity)
    .sync(&db)
    .await?;

Expected Behavior

No error

Actual Behavior

Exec(SqlxError(Database(PgDatabaseError { severity: Error, code: "2BP01", message: "cannot drop index test_table_name_key because constraint test_table_name_key on table test_table requires it", detail: None, hint: Some("You can drop constraint test_table_name_key on table test_table instead."), position: None, where: None, schema: None, table: None, column: None, data_type: None, constraint: None, file: Some("dependency.c"), line: Some(791), routine: Some("findDependentObjects") })))

Reproduces How Often

Every time after the first run (the run creating the table is fine)

Workarounds

Downgrade to sea-orm-2.0.0-rc.32
