Operating system used is linux. I have tried Navicat and SQL Power Architect. They did display relations between tables in the same schema. I have some foreign key constraints which reference tables in a different schema.
Am I missing something with respect to Navicat and PostgreSQL Maestro? Can they not display the inter schema relations?
Is there data visualisation tool for postgresql which is capable of displaying inter schema relations as well?
UPD Sorry for editing your question, but I found it useful. Because this is closed I can not answer (maybe there should be site for that??)
For drawing table relationship of your database you can try this script of GraphViz::DBI perl module.
As result you will get the GIF with relations
