gdb/pgsql: Please support pgsql's _NUMERIC type

[ivothgle]

Go version

go1.23

GoFrame version

2.7.0

Can this bug be reproduced with the latest release?

Option Yes

What did you do?

创建这样的 表

CREATE TABLE "public"."无标题" (
  "id" int4 NOT NULL,
  "n1" numeric(10,2),
  "n2" []numeric,
  PRIMARY KEY ("id")
)
;

如果查询 n2 或者对 n1 进行 ARRAY_AGG(n1) 返回的类型都是 _NUMERIC

What did you see happen?

然后在 https://github.com/gogf/gf/blob/master/contrib/drivers/pgsql/pgsql_convert.go 没有适配这个类型导致无法识别成数组
然后 在 database/gdb/gdb_core_structure.go 匹配中了

		case strings.Contains(typeName, "float") || strings.Contains(typeName, "double") || strings.Contains(typeName, "numeric"):
			return LocalTypeFloat64, nil

导致直接丢失数组，返回 0

What did you expect to see?

请修正
