Well no, that is the specification of -U is the exact opposite of "user
gets inferred from the OS user".

psql: warning: extra command-line argument "bustrac" ignored

You are missing the fact that bustrac is the name of the database so when
you specify the -d option you are being redundant and being told that by
psql.

psql [option...] [dbname [username]]

You like to specify both dbname and username via options but as shown one
can also use arguments.
