Difference between pgAdmin and PostgreSQL
提问by Martin Strejc
Can someone tell me the difference between pgAdmin and postgreSQL? Are both of them one in the same? I can't draw a ER diagram in pgAdmin but was wondering if it's possible in postgreSQL?
有人能告诉我 pgAdmin 和 postgreSQL 之间的区别吗？两者是同一个吗？我无法在 pgAdmin 中绘制 ER 图，但想知道在 postgreSQL 中是否可行？
Once I downloaded the postgreSQL it automatically downloaded the pgAdmin and the postgreSQL database is not in sight.
一旦我下载了 postgreSQL，它就会自动下载 pgAdmin，并且看不到 postgreSQL 数据库。
