What it does
Enables advertising the server’s existence via Bonjour. The default is off. 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; or SELECT name, setting, unit, context, source FROM pg_settings WHERE name = 'bonjour';.
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.
