# title:        Generators are set to 0 after restore
# decription:   
#                   NOTE: FB 4.x has incompatible behaviour with all previous versions since build 4.0.0.2131 (06-aug-2020):
#                   statement 'alter sequence <seq_name> restart with 0' changes rdb$generators.rdb$initial_value to -1 thus
#                   next call of gen_id(<seq_name>,1) will return 0 (ZERO!) rather than 1. 
#                   See also CORE-6084 and its fix: https://github.com/FirebirdSQL/firebird/commit/23dc0c6297825b2e9006f4d5a2c488702091033d
#                   This is considered as *expected* and is noted in doc/README.incompatibilities.3to4.txt
#               
#                   Because of this it was decided to create separate section for check FB 4.x results.
#                   Checked on 4.0.0.2164
#                
# tracker_id:   CORE-3357
# min_versions: ['2.5.0']
# versions:     3.0, 4.0
