Comments

Dataedo reads PostgreSQL comments from following objects:

  • Tables
    • Columns
  • Views
    • Columns
  • Functions

Dataedo does not write comments back to PostgreSQL at this moment.

Known Issues

  • using encoding different than UTF-8 (unicode) causes errors
  • rules are not imported
  • trigger functions are grouped with standard functions
  • dependencies are imported only from views
  • tables and views with no comments, but containing column level comments are not correctly imported. Add a table level comment to solve the issue

Limitations

Following schema elements currently are not supported:

  • Check constraints
  • Non unique indexes
  • Sequences
  • User defined types
  • Domains
  • Extensions
  • Event triggers
