Alexander Korotkov	edf59c40dd	Fix more wrong paths in header comments It appears that there are more files, whose header comment paths are wrong. So, fix those paths. No backpatching per proposal of Tom Lane. Discussion: https://postgr.es/m/CAPpHfdsJyYbOj59MOQL%2B4XxdcomLSLfLqBtAvwR%2BpsCqj3ELdQ%40mail.gmail.com	2018-07-11 17:57:04 +03:00

Andres Freund	dc6c4c9dc2	Add infrastructure for sharing temporary files between backends. SharedFileSet allows temporary files to be created by one backend and then exported for read-only access by other backends, with clean-up managed by reference counting associated with a DSM segment. This includes changes to fd.c and buffile.c to support the new kind of temporary file. This will be used by an upcoming patch adding support for parallel hash joins.
