PostgreSQL and SQL are two different databases.
Both databases are designed for building and analyzing data, and both databases allow you to write code that is much more efficient than a traditional database, like Oracle.
PostgreSQL allows you to run code directly in the database and query data from your own tables.
SQL, on the other hand, is used to store and analyze data in a relational database.
In the simplest terms, SQL stores data in rows of text, while SQL can store data in columns.
SQL allows you write code to run on any number of tables, but in the real world, it is much harder to write SQL than it is to write a traditional relational database because SQL is much simpler to use and understand.
You can write SQL code in a single line, and you can run SQL code from multiple different terminals.
SQL is a programming language that lets you write a program that takes a text file as input and returns a string of characters from that text file.
It’s similar to how a spreadsheet or spreadsheet program can take a file, convert it into a spreadsheet, and then display it in a spreadsheet.
