Established on the localizer; we received a terrain warning from the GPWS. We received vectors and altitudes from Approach. We were monitoring our position and altitude with VOR/DME; GPS with radio altitude chart 10-1R; approach plate; localizer; terrain displayed on ND (Navigation Display) and visual reference. Our position and altitude of 8;200 ft. were certain with a current altimeter setting and all equipment was operational when we received the warning. I have been to this airport numerous times and had never received a terrain warning on this approach. After receiving the warning; I immediately initiated the escape maneuver as per company procedure. The warning went away immediately after initiating the maneuver. We reestablished automation and continued the approach. Being familiar with the area; I was familiar with the hill on approach but should never have received a terrain warning as we were at the appropriate altitude and position. I believe the EGPWS data base should be updated to prevent this from happening in the future.
While being radar vectored for the  ILS approach at 8;200 ft.  received a very short GPWS warning 'pull up'. The Captain complied; but since the message only lasted about 1 second the aircraft never went above 8;300 ft. I'm not really sure why it happened. We were at the Minimum Vectoring Altitude assigned by ATC with terrain on ND (Navigation Display) selected and verified with the GPS symbol on the minimum vectoring chart. The correct altimeter setting was used. A normal approach and landing followed. We never informed ATC since we barely left the assigned altitude.We were at the correct altitude assigned by ATC with the correct altimeter setting. The only thing I can thing is that a hill with an elevation of about 7;100 ft. was just below us and just before intercepting the localizer for the ILS. Possibly warn pilots about the possibility of false GPWS warnings on the airport charts.
A319 Flight Crew reported a Ground Proximity Warning even though they were established at a safe altitude for terrain avoidance.
