If you want PostgreSQL to populate your idmember field with the next value
from the sequence, you need to specify the keyword DEFAULT as its value or
omit it from the INSERT list of coulumns (this assumes you have DEFAULT
nextval('members_idmember_seq') defined on the idmember column).

Should be :

Cmd = "SELECT currval('members_idmember_seq');"

Remember that there's no such thing as auto-increment fields in PostgreSQL
- they are SEQUENCES.
