It was reported in #993 that using an empty `application_name` on connection startup could result in the actual application_name that was set later not being detected. The reason was that we were explicitely not forwarding empty strings from clients as settings to Postgres. This is fixed by simply removing this check. Why we were explicitely ignoring empty strings is not clear to me. But our handling of startup parameters and GUCs has heavily changed over the years, and is able to handle them fine like this.

It was reported in #993 that using an empty
application_nameonconnection startup could result in the actual
application_namethat wasset later not being detected. The reason was that we were explicitely
not forwarding empty strings from clients as settings to Postgres. This
is fixed by simply removing this check. Why we were explicitely ignoring
empty strings is not clear to me. One possible reason is because when
this code was introduced, the empty string was an invalid value for
all of the supported startup parameters. But our handling of startup
parameters and GUCs has heavily changed over the years, and is
able to handle them fine like this and the empty string is a valid
value for
application_name.Fixes #993
