Use safe string copy routine
Using memcpy with strlen as the size parameter will not take theNULL terminator into account, relying instead on the destinationbuffer being properly initialized. Replace with strlcpy which isa safer alternative, and more in line with how we handle copyingstrings elsewhere.Author: Ranier Vilela <ranier.vf@gmail.com>Discussion:https://postgr.es/m/CAEudQApAsbLsQ+gGiw-hT+JwGhgogFa_=5NUkgFO6kOPxyNidQ@mail.gmail.com
