Missing quoting in 'Alias' deparse

[benny-medflyt]

There is a bug in the deparse function when outputting an Alias that has colnames. It doesn't properly quote the alias name and the column names:

pg-query-parser/src/deparser.js

Lines 269 to 273 in 1684b8f

	if (node.colnames) {
	output.push(name + parens(this.list(node.colnames)));
	} else {
	output.push(this.quote(name));
	}

The fix is to call this.quote on the name (just as is done in the "else" branch) as well as this.quote on all the column names.

Here are 2 valid PostgreSQL queries that this library parses correctly, but deparse generates invalid output:

SELECT * FROM generate_series(1, 1) "a#b";

SELECT * FROM generate_series(1, 1) "a#b"("c#d");

Incorrectly is deparsed to:

SELECT * FROM generate_series(1, 1) AS a#b;

SELECT * FROM generate_series(1, 1) AS a#b(c#d);

I can try to create a pull request

I found a similar problem with SQL OVER clauses:

pg-query-parser/src/deparser.js

Lines 1115 to 1119 in 1684b8f

	if (context !== 'window') {
	if (node.name) {
	output.push(node.name);
	}
	}

It should be output.push(this.quote(name));
