How to version control PostgreSQL schema with comments?
Why don't you COMMENT ON the various SCHEMA components, that way your comments are in the schema, and will get dumped.


COMMENT stores a comment about a database object.

To modify a comment, issue a new COMMENT command for the same object. Only one comment string is stored for each object. To remove a comment, write NULL in place of the text string. Comments are automatically dropped when the object is dropped.
