Hello.
I installed centos 6.7 version on virtualbax, have cloned postgres from GitHub.
And then i patched to postgres as the patch file with the following command:
$ patch -p1 < pgbench-expr-abs-9.patch
To make sure that the patch apply to postgres, i wrote two script files.
The script file is:
$ cat before.sql
\set naccounts 100000 * :scale
\setrandom aid 1 :naccounts
$ cat after.sql
\set aid random(1, 100000 * :scale)
Using the script file in pgbench, i run :
$ ./pgbench -T 3 -P 1 -f before.sql
$ ./pgbench -T 3 -P 1 -f after.sql
This was run well. I test for the functions(e.g abs, ddebug, double, exporand, idebug, int, gaussrand, min, max,
random,sqrt) mentioned in the patch, it was also executed without error.
Finally i reviewed code in patch, but did not find to error.
