1) Decoding extension "Slony-II", installed from PGXN, won't connect
2) Install test_decoding
3) Check if decoding is working and you can connect
That's the scenario I'm looking at. It's useful for "is there something
wrong with my decoding setup or is the decoding plugin broken?"
And I can imagine quite a few users who don't have source installs
needing to check that. That doesn't mean test_decoding needs to stay in
contrib, just that it needs to be somewhere which goes into some common
package.
