Yes.

If the MachineB postgres version is older then you may have problems.

MachineA
pg_dump machineadb > madb.sql

copy madb.sql across to machineB

MachineB
psql < madb.sql

This would make a copy of the database named machineadb, if you want
every db on the server then you can use pg_dumpall

You may need options like -U -h and -W (username/host/prompt for
password) man psql or man pg_dump for more detail

Feel free to compress the file to reduce transfer times etc.

You can also reduce it to one step -

pg_dump machineadb | psql -h remotename
