I was just trying out 9.0a4 and I noticed. That I can't connect to pgbouncer with psql from 9.0a4 as a result of the set application_name changes to psql.
I imagine this is really mostly pgbouncer's problem, but I couldn't figure out how if it was possible to make psql not set application_name from the psql man page. If not, at least from a users point of view psql 9.0a4 looks incompatible with existing versions of pgbouncer in at least in this configuration that works with an older versions of psql. ... or, is that a crazy way to look at it?
