ISSUE:       2165
TITLE:       Field subtype of DEC_FIXED columns not returned by isc_info_sql_sub_type
DESCRIPTION:
    When requesting the subtype of a NUMERIC or DECIMAL column with precision in [19, 34]
    using isc_info_sql_sub_type, it always returns 0, instead of 1 for NUMERIC and 2 for DECIMAL.
JIRA:        CORE-5728
FBTEST:      bugs.core_5728
NOTES:
    [30.10.2019] pzotov
        Adjusted expected-stdout to current FB, new datatype was introduced: numeric(38).
    [25.06.2020] pzotov
        4.0.0.2076: type in SQLDA was changed from numeric to int128 
        (adjusted output after discussion with Alex about CORE-6342).
    [13.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
