Thread: pg_stat_statements: remove redundant function call in pg_stat_statements_internal

Hi,

I found some redundant function calls in
pg_stat_statements.c/pg_stat_statements_internal(),
There is no need to call GetUserId() again because the value was
previously obtained.
so I propose a patch to fix it.

--- a/contrib/pg_stat_statements/pg_stat_statements.c
+++ b/contrib/pg_stat_statements/pg_stat_statements.c
@@ -1508,7 +1508,7 @@ pg_stat_statements_internal(FunctionCallInfo fcinfo,
        pgssEntry  *entry;

        /* Superusers or members of pg_read_all_stats members are allowed */
-       is_allowed_role = is_member_of_role(GetUserId(),
ROLE_PG_READ_ALL_STATS);
+       is_allowed_role = is_member_of_role(userid, ROLE_PG_READ_ALL_STATS);

        /* hash table must exist already */
        if (!pgss || !pgss_hash)

Indeed.  I doubt it will make any real difference but it doesn't hurt to fix
it.

Patch looks good to me.

Yes, let's clean up that on HEAD.  No objections from here.  I'll do
that tomorrow or so.
