You can have as many as your machine's hardware will support; there is a
default allowance of 100, but this can be changed to whatever number you
like.  However, each extra backend requires a certain amount of extra
memory, so the practical limit is set by your RAM and by the ability of
your processor(s) and I/O to cope with multiple simultaneous queries.

You will need to configure the Linux kernel to allow sufficient shared
memory and other required system resources.
