postgresqlHow do I set the PostgreSQL work_mem parameter?
The work_mem
parameter sets the amount of memory to be used by the server while performing internal operations such as sorting and hashing. To set this parameter, you can use the ALTER SYSTEM
command.
For example, to set the work_mem
parameter to 1MB, you can run the following command:
ALTER SYSTEM SET work_mem = '1MB';
The output of this command should be:
ALTER SYSTEM
The parts of this command are:
ALTER SYSTEM
: This command is used to modify the configuration parameters of the PostgreSQL server.SET work_mem
: This sets the value of thework_mem
parameter.'1MB'
: This is the value of thework_mem
parameter. This can be any value between1KB
and64MB
.
