Why do we need --no-check-certificate? (we don't need it above; also, well, it's not secure)

I faced the below error when building the image. Switched to maven now.
Step 11/14 : RUN wget -nv --no-check-certificate "https://jdbc.postgresql.org/download/postgresql-42.3.5.jar"
---> Running in 5755549870dd
WARNING: cannot verify jdbc.postgresql.org's certificate, issued by ‘/C=US/O=Let's Encrypt/CN=R3’:

yum install ca-certificates

installing ca-certificates is definitely better than --no-check-certificate
