Good day, I have a PostgreSQL 8.4 database installed on WinXP x64 with very heavy writing and updating on a partitioned table. Sometimes within one minute, there are tens of file with size=1,048,576kb (such as filenode.1,filenode.2,...filenode.43) created in the database subdirectory within PGDATA/base. This caused the disk space quickly used up. Is this expected? Thanks for any information Best Regards Rose Zhou -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
