What it does
Specifies the Bonjour service name. The computer name is used if this parameter is set to the empty string ” (which is the default). This parameter is ignored if the server was not compiled with Bonjour support. This parameter can only be set at server start.
(Description quoted from the official PostgreSQL documentation.)
How to apply a change
Set it in postgresql.conf (or with ALTER SYSTEM) and restart the server — this parameter cannot change without a restart.
Inspect the current value and source with SHOW bonjour_name; or SELECT name, setting, unit, context, source FROM pg_settings WHERE name = 'bonjour_name';.
Tuning guidance
This is a connectivity or security setting, not a performance knob. Choose the value from your security and network requirements (TLS files, ciphers, keepalives, authentication behaviour) rather than for throughput, and verify it against your organization’s policy. Test changes in staging, because a wrong value here can lock clients out.
