Syntax Checking SQL Statements/Schema/Queries using pgsanity

While trying to _hand_-write an SQL for _this_ tutorial, I had a cryptic error:
https://travis-ci.com/dwyl/learn-postgresql/builds/106420820#L508

# `{ error: syntax error at or near "("`

In a file with 60 lines and **thirty** opening parentheses **`"("`**


This error message is about as helpful as sunscreen on a submarine ...

So I went hunting for a syntax checker and found: https://github.com/markdrago/pgsanity

```
$ pgsanity schema.sql
line 24: ERROR: syntax error at or near "("
```
So at least I know what _line_ the error is on.
