# title:        Bad PLAN generated for query on Firebird v3.0
# decription:   
#                    Test is based on data from original database that was provided in the ticket by its author.
#                    Lot of data from tables were removed in order to reduce DB size.
#                    Reproduced bug on 3.0.2.32708, 4.0.0.800
#                    Wrong plan was: 
#                        PLAN JOIN (A NATURAL, C INDEX (PK_EST_PRODUTO), B INDEX (PK_COM_PEDIDO))
#                    Elapsed time was more than 1.2 second.
#               
#                    All fine on:
#                        3.0.3.32838: OK, 5.922s.
#                        4.0.0.801: OK, 6.547s.
