Allow go_struct_tag to be applicable to aliases

[dandee]

What do you want to change?

I'd like to see go_struct_tag to be applicable to aliases to column names.

Version

1.29.0

What happened?

sqlc does not allow to apply custom struct tag to aliases in the generated structs returned by query functions.

In the provided Playground URL I'd like to see GetTestRow struct to be annotated as following in the "db.query.sql.go":

type GetTestRow struct {
	ID         int64
	Name       string `tstype:"SomeType"`
	CategoryID sql.NullInt64
	Count      int64 `tstype:"AnotherType"`
}

Database schema

CREATE TABLE parts (
  id   BIGSERIAL PRIMARY KEY,
  name text      NOT NULL,
  category_id BIGSERIAL
);

SQL queries

-- name: GetTest :many
SELECT *, count(*) AS count
FROM parts;

Configuration

{
  "version": "2",
  "sql": [{
    "schema": "schema.sql",
    "queries": "query.sql",
    "engine": "postgresql",
    "gen": {
      "go": {
        "out": "db",
        "overrides": [
          {
        	"go_struct_tag": "tstype:\"SomeType\"",
            "column": "*.name"
          },
          {
        	"go_struct_tag": "tstype:\"AnotherType\"",
            "column": "*.count"
          }
        ]
      }
    }
  }]
}
