Thread: pgsql: Fix memory overrun when querying pg_stat_slru
Fix memory overrun when querying pg_stat_slru pg_stat_get_slru() in pgstatfuncs.c would point to one element after the end of the array PgStat_SLRUStats when finishing to scan its entries. This had no direct consequences as no data from the extra memory area was read, but static analyzers would rightfully complain here. So let's be clean. While on it, this adds one regression test in the area reserved for system views.
