The cheat is to read the on disk file and write it into an in memory file and then use that with STDIN. Something like:
sql_copy = "COPY " + self.pg_tbl_name
sql_copy += " FROM STDIN WITH CSV DELIMITER '\t'"
cur_copy.copy_expert(sql_copy, mem_file)
And you don't actually need a "memory file", any object implementing "read" method, such as a normal fie object should just work:
file=open('1.txt', 'r')
cur_copy.copy_expert(sql_copy, file)
