Hello,
I noticed buildint2vector / buildoidvector assigns lbound1=0 as default
value, but array type shall have lbound1=1 in the default.
Is there some reasons for the difference?
When I made a simple C-function that returns result of int2vector which
carries attribute numbers of the argument.
postgres=# select attnums_of('t0','{aid,cid,bid}');
attnums_of
---------------
[0:2]={3,5,4}
(1 row)
Once it assigns lbound1=1 manually,
postgres=# select attnums_of('t0','{aid,cid,bid}');
attnums_of
------------
{3,5,4}
(1 row)
Maybe, the later one is natural.
Of course, these APIs are mostly internal, so lbound1 setting is not
significant so much.
Thanks,
