PostgreSQL For Beginners (Udemy.com)

Very Basic :(

good flow

No Linux install steps.

Poderia ter outros tipos de instalação, por exemplo em Mac ou Linux.

Straight to the point and well explained

very clear

Great course for a complete beginner.

The explanation is very shallow and uninsightful. Many times the teacher just rephrases the names of the things on the screen without useful explanation. For example, even at chapter 2, he hasn't explained what are scripts, dependencies, and "schemas" is sorely lacking: what's a "logical container"? What does he mean by "other database objects"?

I will most likely request for a refund if the remaining videos do not reflect a higher quality of content. I am learning PostgreSQL completely from scratch, but I've learned basic SQL functions before.

This course is absolute beginner level, which is fine. It will not be useful to someone who already has some SQL experience who e.g. needs to know what is particular to PostgreSQL, and many important details are glossed over or not mentioned. (e.g. subtleties of different data types, why you would choose some over others for certain purposes; how do different versions of SQL vary on certain clauses, functions; how to deal with temporal data; no mention of WITH clauses; etc.)

The videos really needed to be edited, some parts better organized. All of the videos appear to have been made in one take with no edits. Some typos. Unnecessary repetition between videos. Presentation is very slow; I had to watch it at 1.5x and 2.0x speed. Even so I did learn some things about pgAdmin and aspects of SQL that I rarely use.

Enjoyed the course and found it very informative, I have never used PostgreSQL before so found the information very helpful.

The delivery is very dry. Fortunately, I'm drinking coffee or I'd be falling asleep by now (even the coffee wasn't enough at times). A lot of time wasted showing us over and over how to find pgAdmin and enter the password. Some of his explanations miss the point. For example, the "CROSS JOIN" lecture never explains what a cartesian product is and the repeated emphasis on combining all of the columns, rather than rows, gives an incorrect impression at best. The examples are trivial and meaningless for the most part. These constructs are useful to answer real business problems and make more sense when illustrated in that manner. The amount of information you actually get from this course could be covered in a an hour or two. The delivery is slow, boring, and uninformative. Except for one or two concepts that are unique to Postgres, this is a poor intro to SQL course. There are much better courses (see Khan Academy) which may or may not use Postgres for their examples. At this level, the database is largely immaterial. Don't waste your time and money on this course.
