When parsing SQL in PostgreSQL dialect, allow unquoted table names to contain dollar sign, letters with diacritical marks and non-Latin letters

According PostgreSQL documentation [1][2]:
SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

Letters with diacritical marks and non-Latin letters are extended ascii letters (character code 128-255 or in octal \200-\377)[3].
