  Aims. Planetary nebulae (PNe) are a brief phase of stellar evolution and as
such some of the rarest objects in our galaxy. Accurate identification of PN
central stars (CSPNe) in large surveys such as Gaia is key to exploiting the
scientific potential of those surveys for the study of PNe and stellar
evolution. Methods. We apply our automated search method to identify source
detections corresponding to CSPNe and compact PNe in the recently released Gaia
Early Data Release 3 (EDR3). The method is updated to incorporate photometric
uncertainties. Results. The new catalogue offers improved completeness and
accuracy over the previous one, and will continue to be valid for the upcoming
Gaia Data Release 3 (DR3). The identification of EDR3 sources unlocks the
improved astrometry and photometry stemming from calibration updates and a
longer mission duration, even for sources that have previously been identified.
