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
- Casts
