Feat: PostgreSQL Support & fixes

[zhiyan114]

PostgreSQL is a popular choice for remote database and better than mysql.

PR also a resolves #156

[Sayrix]

In the comments of your driver postgre you say that it's taken from the quick.db pre-release but in that case why not wait for quick.db to support it directly rather than using experimental code?

[zhiyan114]

It seems like all database driver formats are the same for the library. It's stable enough, they're probably waiting a bit longer to add other changes before releasing it.

[Sayrix]

Can you try your code and say me if every functions of ticket-bot works ?

[Sayrix]

Especially the emojis in the db

[zhiyan114]

Sure, though, I'll be later tonight since I won't be available near the dev PC for the day

[zhiyan114]

The emoji won't be a problem, since Postgres already know how to handle that. The only issue I found is the default config table name that I initially set to, which conflicts with SQL's keyword. Other than that, it works like normal.

I'll def make another PR once quick.db push out the driver to clean stuff up, tho I do recommend you to plan to move away from squick.db because how inefficient it is at using database.
