pipe text to copy statement stdin input

Hi all,

Is there a way to pipe text into a COPY statement's stdin input using
cmd-line psql?

I'm using the following syntax to enter large strings of text into a
table. The text itself has a json-like syntax that has the potential
for carrying numerous special characters.

COPY mytable(name, description, text) FROM stdin;
<the text>
\.

Problem is that my terminal's copy-paste buffer is much smaller than
the text I need to insert.

Note:
- I do not have superuser perms for the db, so passing a file instead
of stdin is not an option.

- Ditto for using \i to import a file.

- The db is password protected, so invoking `psql` as a non-
interactive command may not be possible. Right?

- If I'm wrong, anyone have example syntax of how to create a valid
COPY statement? I've found an interesting OSX cmd-line util that
copies/pastes between Terminal and the "pasteboard." Though I think
this just gets bitten by the file restriction anyway, eg:

% cat bigfile.txt > pbcopy
% psql DBNAME USERNAME (PASSWORD???) <<EOF
COPY mytable(name, description, text) FROM stdin;
pbpaste > stdin(???)
\.

Terminal

Suggestions greatly appreciated!

Thanks
Scott
