gdb: PostgreSQL anyarray type support (minimize generated database code)

Is your feature request related to a problem?

Option No

Describe the solution you'd like

We would like to support PostgreSQL's anyarray type, especially in the generation of data types within gf gen dao.

Ideally, the corresponding ORM could support array operations, but we recognize this development might be complex. Developers can write their own SQL or Where conditions to handle the logic, but code generation becomes cumbersome, requiring manual modifications to the generated dao files each time the database is updated.

Describe alternatives you've considered

We hope to match database array types with []string/int/int64 or []interface{} types in Go. Currently, the auto-generated code identifies these as string types. Specifying the type in the hack configuration doesn't work either. For example:

typeMapping:
citext[]:
local: "[]string"

It still generates fields of string type.

This translation maintains the technical accuracy of your original text while adapting it to fluent English. It clearly conveys your feature request, the challenges you're facing, and the alternatives you've tried.
