What is the URL where the issue is happening

https://roadmap.sh/postgresql-dba

What browsers are you seeing the problem on?

No response

Describe the Bug

The current columns official doc points to https://www.postgresql.org/docs/current/infoschema-columns.html

However I believe it would be better to link it to this https://www.postgresql.org/docs/current/ddl-alter.html

Output from browser console (if any)

Hey also found a broken link in the Object Model section.

The following link is broken
@article@PostgreSQL Server and Database Objects

I guess we want this link
https://neon.com/postgresql/postgresql-tutorial/postgresql-server-and-database-objects

If its okay I can fix this in the same PR as well :)
