This parameter determines whether the passphrase command set by

<varname>ssl_passphrase_command</varname> will also be called during a

configuration reload if a key file needs a passphrase. If this

parameter is off (the default), then

parameter is<literal>off</literal> (the default), then

<varname>ssl_passphrase_command</varname> will be ignored during a

reload and the SSL configuration will not be reloaded if a passphrase

is needed. That setting is appropriate for a command that requires a

TTY for prompting, which might not be available when the server is

running. Setting this parameter to on might be appropriate if the

passphrase is obtained from a file, for example.

This parameter must be set to <literal>on</literal> when running on

will perform a configuration reload due to the different process model

of that platform.

This parameter can only be set in the <filename>postgresql.conf</filename>
