Hi
I have a new postgresql 9.5.0 installation on a new virtual server debian
8.3 x64 with 4gb RAM, I have compiled postgresql from source.

When I import a dump with materialized views I see that postgres process
takes about all 4 Gb and then I have this error

fork: Cannot allocate memory

Can anyone help me?

Thanks in advantage :)

Enrico
