There's no such functionality. You'll need to create the account prior
to installing PostgreSQL, and set the flags then.

TIP 2: Don't 'kill -9' the postmaster

it could be created with a command line like...

NET USER username password /EXPIRES:NEVER /ADD ...

...run prior to the 'silent installation'.
