Hi,
Thanks Amit for fixing review comments.
I reviewed v48 patch and below are some comments.
1.
+ * based on the number of indexes. -1 indicates a parallel vacuum is
I think, above should be like "-1 indicates that parallel vacuum is"
2.
+/* Variables for cost-based parallel vacuum */
At the end of comment, there is 2 spaces. I think, it should be only 1
space.
3.
I think, we should add a test case for parallel option(when degree is not
specified).
*Ex:*
postgres=# VACUUM (PARALLEL) tmp;
ERROR: parallel option requires a value between 0 and 1024
LINE 1: VACUUM (PARALLEL) tmp;
^
postgres=#
Because above error is added in this parallel patch, so we should have test
case for this to increase code coverage.
