需要迁移一个第三方的数据库到本地，不清楚原数据库名称

如题，只有 dump 出的 SQL 文件，部分内容截取如下：

--
-- PostgreSQL database dump
--

SET client_encoding = 'SQL_ASCII';
SET standard_conforming_strings = off;
SET check_function_bodies = false;
SET client_min_messages = warning;
SET escape_string_warning = off;

--
-- Name: plpgsql; Type: PROCEDURAL LANGUAGE; Schema: -; Owner: postgres
--

CREATE PROCEDURAL LANGUAGE plpgsql;


ALTER PROCEDURAL LANGUAGE plpgsql OWNER TO postgres;

SET search_path = public, pg_catalog;

--
-- Name: res_set; Type: TYPE; Schema: public; Owner: postgres
--

CREATE TYPE res_set AS (
	pidnum integer,
	nret smallint
);


ALTER TYPE public.res_set OWNER TO postgres;

--
-- Name: account_login(character varying, character varying, character varying); Type: FUNCTION; Schema: public; Owner: spiritking
--

CREATE FUNCTION account_login(character varying, character varying, character varying) RETURNS res_set
    AS $_$declare
ppAccountID ALIAS FOR $1;
pPassword ALIAS FOR $2;
pClientIP ALIAS FOR $3;
pAccountID varchar(20);
pcount int;
pPwd char(32) default null;
pBAuthority int2 default 0;
pGMIP varchar(15) default null;

res res_set;

BEGIN
pAccountID = lower(ppAccountID);
res.nRet=-1;
...

请教如何确定原数据库的名称呢？

纯外行请教 查到了挺多关于 PostgreSQL 数据库迁移的教程，但是就没有一个提及数据库名称的 或者 PostgreSQL 对数据库命名不敏感？可以随便改名？
