When reporting connection errors, we might show a database name in the message that's not the one we actually tried to connect to, if the database was taken from libpq defaults instead of from user parameters. Fix such error messages to use PQdb(), which reports the correct name. (But, per commit 2930c05634bc, make sure not to try to print NULL.) Apply to branches 9.5 through 13. Branch master has already been changed differently by commit 58cd8dca3de0.
