Greetings,
I need to implement the classical problem of threaded comments in a Postgresql
database. I know that the upcoming 8.4 release includes Common Table
Expressions, so I have to ask: is this feature the mother-of-all-solutions
to the threaded comments problem, or is it still worth investigating ltree?
Also, lots of people mention Joe Celko's book on this subject. Is it still
a valid resource, or do CTE's make it obsolete?
Thank you!
C.S.
