读取PostgreSQL 数据库中 Database 名称等的信息

从 oid2name的代码里扒出来的：

postgres=# SELECT d.oid AS Oid,datname AS DatabaseName,spcname AS Tablespace

postgres-#  FROM pg_catalog.pg_database d JOIN pg_catalog.pg_tablespace t 

postgres-#  ON  (dattablespace = t.oid) order by 2;

  oid  | databasename | tablespace 

-------+--------------+------------

 12788 | postgres     | pg_default

 12783 | template0    | pg_default

     1 | template1    | pg_default

(3 rows)



postgres=#
