Can I Modify the temp_file_limit Parameter for My RDS for PostgreSQL Instance?
Parameter Description
The temp_file_limit parameter specifies the maximum amount of storage space that a PostgreSQL process can use for temporary files.
When SQL statements are executed, temporary files, such as sort files and hash files, are generated. Any transaction using temporary files whose total size exceeds this limit will be terminated. For details, see temp_file_limit.
Parameter Modification
You can modify temp_file_limit on the RDS console. For details, see Modifying Parameters of an RDS for PostgreSQL Instance.
Precautions
Executing SQL statements or backing up or restoring data will generate temporary files. If the total size of temporary files exceeds the value of temp_file_limit, the operation fails. The value of temp_file_limit should not be too small.
temp_file_limit can be set to -1, indicating that the size of temporary files is not limited. To prevent too many temporary files from using up the storage space and causing service unavailability, do not set temp_file_limit to -1. In most cases, keep the default value for temp_file_limit.
