You should probably rethink that schema. A lot of similar tables can be folded into one table with an extra key column. Also, where did you get the idea that 2000 tablespaces would be a good thing? There's really no point in more than one per spindle or filesystem. > Although after the initial inserts to about 32000 tables the subsequent > inserts are considerable fast, subsequent inserts to more than 32000 tables > are very slow. This has probably got more to do with inefficiencies of your filesystem than anything else --- did you pick one that scales well to lots of files per directory? > This seems to be due to the datatype (integer) of max_files_per_process > option in the postgres.conf file which is used to set the maximum number of > open file descriptors. It's not so much the datatype of max_files_per_process as the datatype of kernel file descriptors that's the limitation ... regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
