Re: Function problem

Sharon,

you can set the session user using set session authorisation.

see:
http://developer.postgresql.org/docs/postgres/sql-set-session-authorization.
html and
http://developer.postgresql.org/docs/postgres/sql-copy.html

regards

steve boyle

P.S. did you mean to include the \ in the function below?
