Hi guys, migrate from 8.4 to 9.5, all OK except that 2-3 days pass and the database experiences slowness, I execute the linux top command and it shows me a postgres user process executing a strange command (2yhdgrfrt63788) that I consume a lot of CPU, I see the querys active and encounter select fun ('./ 2yhdgrfrt63788') , this did not happen in version 8.4, any help would appreciate it.
