An other way is to log evictions, it provides informations about time and
amount :
for (i = 0; i < nvictims; i++)
{
hash_search(pgssp_hash, &entries[i]->key, HASH_REMOVE, NULL);
}
pfree(entries);
/* trace when evicting entries, if appening too often this can slow queries
...
* increasing pg_stat_sql_plans.max value could help */
ereport(LOG,
(errmsg("pg_stat_sql_plans evicting %d entries", nvictims),
errhidecontext(true), errhidestmt(true)));
