Fix handling of escape sequences in postgres_fdw.application_name
postgres_fdw.application_name relies on MyProcPort to define the data
that should be added to escape sequences %u (user name) or %d (database
name). However this code could be run in processes that lack a
MyProcPort, like an autovacuum process, causing crashes.
The code generating the application name is made more flexible with this
commit, so as it now generates no data for %u and %d if MyProcPort is
missing, and a simple "unknown" if MyProcPort exists, but the expected
fields are not set.
