Hi Sawada Masahiko,
I liked this feature. So I have reviewed it.
Changes are straight forward and looks perfect.
No issues found with make/make install/initdb/regression.
However I would suggest removing un-necessary braces at if, as we have only
one statement into it.
if (++cur_line >= INT_MAX)
{
cur_line = 1;
}
Also following looks wrong:
postgres[1]=# select
postgres[2]-# *
postgres[3]-# from
postgres[4]-# tab;
a
---
(0 rows)
postgres[1]=# select
*
from
tab
postgres[2]-# where t > 10;
ERROR: column "t" does not exist
LINE 5: where t > 10;
^
Line number in ERROR is 5 which is correct.
But line number in psql prompt is wrong.
To get first 4 lines I have simply used up arrow followed by an enter for
which I was expecting 5 in psql prompt.
But NO it was 2 which is certainly wrong.
Need to handle above carefully.
Thanks
