Is it possible to increase the length of an array?
I have tried adding length: 2048 and re-created the migrations (deleted migrations, dropped db, created db, and created new migration). It shows as missing_deposit_dates TEXT DEFAULT NULL
Running Symfony 6, PHP 8.2, PostgreSQL.
Column
#[ORM\Column(type: 'array', length: 2048, nullable: true)]
private ?array $missingDepositDates = [];
Exception
> An exception occurred while executing a query: SQLSTATE[22001]: String
> data, right truncated: 7 ERROR: value too long for type character
> varying(255)

It is setting your property as TEXT because the attribute length only applies to string columns.
There is no size limit on PostgreSQL arrays. This will make your make:migration command pass successfully:
#[ORM\Column(nullable: true)]
private ?array $missingDepositDates = [];
To limit the array length I would do it when I persist the changes of the entity in my PHP code. You could validate if the length of the current array is less than 2048 before persisting the changes.
