Dear Sir/Madam,
My name is Jixue Liu, a PhD student in the School of Computer Science,
University of South Australia. I am studying view maintenance in OR
Systems. The model I study most and the system I use is Postgres. I
appreciate Postgres group for the contribution to the field. Now I have
some questions about the usage of the system.
1. How to define a relation with an attribute which takes values of sets
of strings?
2. What is the syntax to define a table referring another table?
3. How to use the number in pg_inherits to get relation names?
I am looking forward to hearing from you.
Jixue Liu
