ISSUE:       https://github.com/FirebirdSQL/firebird/issues/3179
TITLE:       ISQL extracts the array dimensions after the character set name rather than after datatype and its length
DESCRIPTION:
JIRA:        CORE-2788
FBTEST:      bugs.core_2788
NOTES:
    [05.10.2023] pzotov
    Removed SHOW command for check result because its output often changes. Query to RDB$ tables is used instead.
