Seems the problem was introduced here:

http://developer.postgresql.org/cvsweb.cgi/pgsql/src/bin/pg_dump/pg_backup_db.c.diff?r1=1.58;r2=1.59

(I could just revert the code to using PQdb(), but I don't think there's
a need to mention the database in the error message ourselves --
PQerrorMessage() should include that information if appropriate.)
