ISSUE:       6408
TITLE:       SUBSTRING SIMILAR is described with wrong data type in DSQL
DESCRIPTION:
JIRA:        CORE-6159
FBTEST:      bugs.core_6159
NOTES:
    [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.
