Looks that pg_check doesn't compile with/for Pg 11

[ghost]

I tried to get it installed, but "make" fail.

System: Ubuntu Bionic, with Pg:

# dpkg -l | awk '$1=="ii" && $2 ~ /postgresql.*11/ {printf "%-35s : %s\n", $2, $3}' | sort
postgresql-11                       : 11.3-1.pgdg18.04+1

got fresh clone, and tried to compile it:

Does the code need some update, or did I screw something up?
