Public key to verify signature of latest PGAdmin version?

Hi,

What's the public key I need to verify the signature file (dmg.asc) to
install the .dmg of the latest version?

I'm new to GPG, sorry if I'm messing up any terms. I am starting by using the
instructions at GPGTools for verifying any downloaded file.
