Postgresql 9.3
I am downloading data that I want to import into a table. The data comes
in tab delimited, CRLF format.
I am using plpython to get the data and I wanted to use copy with stdin
to import it without having to save it to a file.
To do this, I am setting sys.stdin to a StringIO object with my data inside.
Not sure that is going to work as:
STDIN
Specifies that input comes from the client application.
I would say a plpython function is actually running as the server and is
not a client.
However, when I call copy I am getting SPI_ERROR_COPY, which the docs
define as "if COPY TO stdout or COPY FROM stdin was attempted" which is
exactly what I am trying to do (so the error is logical).
Is there another method of loading delimited data in bulk without saving
it as a file?
I do it by pushing the data in using a Python script that uses the the
COPY FROM/TO methods of psycopg2:

Thanks
