One problem is the only way for a client tool to work generically in provding
data entry forms would be to provide entry for all columns, which would break
in all but the most trivial of cases. Last time we discussed this for
phppgadmin, the general opinion was it wasn't worth trying to work around
postgresql core's deficiency. Once the core postgresql server supports
updatable views in proper, I'd imagine this would get done.
