psql not found in latest image for postgres16

[linuxnow]

When I start the image I get his error:

/usr/local/bin/entrypoint: cd: line 15: can't cd to /opt/postgresql-client-collection/16: No such file or directory

fetch https://dl-cdn.alpinelinux.org/alpine/v3.18/main/x86_64/APKINDEX.tar.gz

ERROR: *.apk: No such file or directory

/usr/local/bin/entrypoint: line 19: psql: not found

I seems it cannot download psql.

I'm checking the Dockerfile and I see that postgres 16 is not supported. I'll try to make a fix and send a pull request,
