stats_temp_directory
A system parameter determining the directory for temporary statistics data
stats_temp_directory is a configuration parameter determining the location of the directory for storing temporary statistics data in.
stats_temp_directory was added in PostgreSQL 8.4 and removed in PostgreSQL 15.
Usage
By default, temporary statistics data is stored in the pg_stat_tmp directory within the data directory. However it may be desirable to use a custom location such as a RAM-based disk for better performance; this can be achieved by setting stats_temp_directory.
From PostgreSQL 15, temporary statistics are stored in memory by default so stats_temp_directory will no longer be available.
Default value
The default value for stats_temp_directory is: pg_stat_tmp.
