PVS means "Potentially Visible Set" and was invented by John Carmack for Quake.
All Quake-based engines use it for extremely rapid visibility culling.
At map compile time, each node in the world's BSP tree gets a list of all other BSP tree nodes that are wholly or partially visible from that particular node. When the drawing frame is rendered and the BSP tree is being traversed to find objects to draw, any node not in the current PVS can be safely ignored.
The map building tool VIS (for Quake) is what generates this information and adds it to the BSP map file.

This is probably the stupidest question asked here but what in the heck is a PVS ?
