Please ignore the above email. I've understood the reason as below:
Because of 2 rules:
1. create rule rtest_t4_ins2 as on insert to rtest_t4
where new.a >= 20 and new.a < 30 do
insert into rtest_t6 values (new.a, new.b);
2. create rule rtest_t6_ins as on insert to rtest_t6
where new.a > 25 do instead
insert into rtest_t8 values (new.a, new.b);
The insertion doesn't happen in rtest_t6 rather is forwarded or been done into rtest_t8.
Pardon me.
Thanks

Hi Team,I'm writing to clarify one of the expected output in rules.out file.Why does value at this line https://github.com/postgres/postgres/blob/913c60b067aa1a618420fd0372c4df3cf5501863/src/test/regress/expected/rules.out#L594 for rtest_t6 is zeros. When we have defined the rule for rtest_t6 as:create rule rtest_t4_ins2 as on insert to rtest_t4
where new.a >= 20 and new.a < 30 do
insert into rtest_t6 values (new.a, new.b);Therefore:At https://github.com/postgres/postgres/blob/913c60b067aa1a618420fd0372c4df3cf5501863/src/test/regress/expected/rules.out#L576 / insert into rtest_t4 select * from rtest_t9 where b ~ 'and t8';Shouldn't insert the rows with value as 26 and 28 as well. Isn't it ? as rules says to insert the rows in rtest_t6 tables if value is from 20(inclusive) to 30 (exclusive).Please help me with the clarification.ThanksManav
