[HACKERS] pgsql_tmp and external sort
Dear Hackers Recently I find about pgsql_tmp directory. As I think, this directory is a area for making temporal files which are used for external sort. I wonder if anyone could help me to find the module of pg that is responsible for the temporal space and external sort in the PG source code. Regards Soroosh Sardari

See src/backend/utils/sort/tuplesort.c and src/backend/storage/file/buffile.c for starters. - Heikki -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

From: Soroosh Sardari soroosh.sard...@gmail.com I wonder if anyone could help me to find the module of pg that is responsible for the temporal space and external sort in the PG source code. See src/backend/utils/sort/ for sort implementation. That uses BufFile in src/backend/storage/file/buffile.c, which in turn uses OpenTemporaryFile in src/backend/storage/file/fd.c.
