The pg_collation check referenced colllocale unconditionally. That column
only exists on PostgreSQL 17+; 15-16 call it colliculocale and <= 14 keep
the ICU locale in collcollate, so the query failed with "column does not
exist" on anything older than 17. Read the columns through to_jsonb(c),
which tolerates missing keys. Verified against postgres:14, :16 and :17 —
all return icu_provider = t, locale = bn-BD.
The reviewer's regex rule flagged `\w` unconditionally. In Python str
patterns `\w` does match Bengali letters, but not vowel signs or hasanta
(category M), so `re.findall(r'\w+', 'রহিম')` gives ['রহ', 'ম']. Say
that precisely, note where `\w` is ASCII-only (JavaScript, re.ASCII), and
point at [ঀ-] or \p{Bengali} instead.
