Adds a --quote-all option to the command line

[Adam-Mustafa]

Adds a --quote-all option to the command line which will make all column names be wrapped in quotes, not just the ones that need to be.

Pull request overview

This PR adds a --quote-all command-line flag that forces all identifiers (table names, column names, schemas) to be wrapped in double quotes, regardless of whether they are PostgreSQL reserved words or contain special characters requiring quotation.

Key changes:

• Introduces new quoting functions that accept a forceQuote boolean parameter
• Propagates the --quote-all flag through the command execution pipeline
• Adds comprehensive test coverage for the new quoting behavior

What's the problem are we trying to solve here? We'd like to avoid adding flags unless absolute necessary

[Adam-Mustafa]

Hi @tianzhou, It's just a choice in the output format. Other tools I've seen quote all values and my concern is that some missing value in the future would cause a break because the keyword is not in the list. At the same time, I didn't want to dramatically change the expected output. So I figured a reasonable middle ground was adding the option as a flag. If that's not in line with the repo, it's not absolutely necessary. It just makes the existing output slightly more brittle but still well within reason.

@Adam-Mustafa thanks for providing the background. For the moment, we are holding off adding such a flag.
