Re: [PATCH] Add features to pg_stat_statements

The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           tested, passed
Documentation:            tested, passed

The patch applies cleanly and looks fine to me. It's a small detail, However wouldn't it be better if the following
changeswere made.
 

1.There are unnecessary difference lines 707 and 863 in "pg_stat_statements.c".
2.There is no comment on "slock_t mutex" in "struct pgssCtlCounter" in "pg_stat_statements.c".
3."update_ctl" and "reset_ctl" are generic and illegible name.You might want to rename it something like
"pgss_ctl_update".
4.To improve the readability of the source, why not change the function declaration option in "pg_stat_statements_ctl"
from
 
"AS 'MODULE_PATHNAME'" to "AS 'MODULE_PATHNAME', 'pg_stat_statements_ctl'"? in "pg_stat_statements--1.8--1.9.sql".

The new status of this patch is: Waiting on Author
