fix: get correct table name if table name is quoted

[HielkeJ]

TABLE_NAME is extracted if the table name is quoted. Should fix #1173

Thank you for your contribution.

@kaylareopelle @hannahramadan would you all mind comparing that to the new relic implementation to see if we are missing anything else?

[hannahramadan]

Thanks @HielkeJ!

I'm wondering if we should remove the single quotes from the regex. @mostfunkyduck pointed out that single quotes are for string literals, not identifiers. What do you think @arielvalentin @scbjans

New Relic does not have this implemented and I didn't see others who did, so unfortunately not a lot to compare to.

[scbjans]

Thanks for pointing that out, I somehow read past that.
After reading those docs, I agree that the single quotes should be removed from the regex, since those aren't for identifiers.

I did a small update in the PR @hannahramadan. If I try in Postgres to to a select SELECT * FROM 'table', it returns a syntax error. I didn't test if it fails in opentelemetry-ruby-contrib as well with a syntax error, but at least in shouldn't run the query.

Given this new information I'm going to rescind my approval and scrutinize this a little more.

I'll leave the final approval to some other folks.

[hannahramadan]

This looks good to me with the recent updates.
