The file open command is:
f = open("/tmp/test.txt","r")
Is this correct? Is the read method syntax correct
Well, it looks correct. Do you get any errors with that?

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)--Alex
