• Fix the PostgreSQL subscription adapter dropping broadcasts to long multibyte stream names.

  PostgreSQL identifiers are limited to 63 bytes, and the adapter hashes any name over that limit to avoid silent truncation. The length check was done on character count rather than byte size, so a multibyte stream name with 63 or fewer characters but more than 63 bytes was silently truncated by PostgreSQL.
