How to display gpg key details without importing it?

Question

I have a copy of the postgresql apt repository gpg key and would like to view the details of the gpg key as it comes in the file. Is this possible without importing it into

Answer 1

I seem to be able to get along with simply:

$gpg 

Which outputs like this:

$ gpg /tmp/keys/something.asc 
  pub  1024D/560C6C26 2014-11-26 Something 
  sub  2048g/0C1ACCA6 2014-11-26

The op didn't specify in particular what key info is relevant. This output is all I care about.
