We would like a new entry on the Comments concept under PostgreSQL. The entry should go in a new file under docs/content/postgresql/concepts/comments/comments.md.

The entry should include:

• An introductory paragraph that describes the concept
• A ‘Syntax’ section that includes the syntax for the concept (if applicable)
• An ‘Example’ section that shows the concept in use

Please refer to the concept entry template, content standards, and markdown style guide when working on the PR for this issue.
