SQL/Parser.php: ARRAY[:param] hits but ARRAY [:param] misses

[millawell]

Bug Report

Q	A
Version	^3.4.0

Summary

A whitespace between ARRAY and the square bracket [ will result in the parser missing the replacement of the :parameter var with ?.

How to reproduce

$QUERY = <<<SQL
        with config as (
            select ARRAY [:parameter] as parameter
        )
        SQL;

does not work but

$QUERY = <<<SQL
        with config as (
            select ARRAY[:parameter] as parameter
        )
        SQL;

works

In Connection.php:1089 ([$sql, $params, $types] = $this->expandArrayParameters($sql, $params, $types);),
the ARRAY [:parameter] should be replaced with ARRAY[?].

I guess it comes down to modifying the regex in Parser.php@BRACKET_IDENTIFIER
