I added a few "raise notice" commands to your function, and got this:
NOTICE: sub_idcol = invisible_id
NOTICE: default_exp = nextval('public.e_mail_address_invisible_id_seq'::text)
NOTICE: sequence_name = public.e_mail_address_invisible_id_seq
NOTICE: not found
NOTICE: sub_idcol = pop_id
NOTICE: default_exp = nextval('pop_seq'::text)
NOTICE: sequence_name = pop_seq
NOTICE: found
ERROR: relation "e_mail_address_invisible_id_seq" already exists
CONTEXT: SQL statement "CREATE SEQUENCE public.e_mail_address_invisible_id_seq;"
PL/pgSQL function "gen_sequences" line 51 at execute statement
The problem seems to be that you're not accounting for a schema name
possibly appearing in nextval's argument.
