Example: create temporary table foo (a int); insert into foo values (1); alter role peter set temp_buffers = 120; ERROR: 22023: invalid value for parameter "temp_buffers": 120 DETAIL: "temp_buffers" cannot be changed after any temporary tables have been accessed in the session.
Another example: set log_statement_stats = on; alter role peter set log_parser_stats = on; ERROR: 22023: invalid value for parameter "log_parser_stats": 1 DETAIL: Cannot enable parameter when "log_statement_stats" is true. Another example is that in <=9.1, ALTER DATABASE ... SET search_path would check the existence of the schema in the current database, but that was done away with in 9.2. The first example could probably be fixed if check_temp_buffers() paid attention to the GucSource, but in the second case and in general there doesn't seem to be a way to distinguish "assigning per-database setting" and "enacting per-database setting" as a source.
