hi Michael,
thanks for your references, the problem is that what I want is not to type anything in console (psql) but to construct an automatic insertion to Db (when the user uploads a "text" (.csv, .txt file) and send it to my server, then it runs "something" to insert into a table). Shortly, what I want is to let users see his point data (species occurences) in my web application; when session finishes, data should disappear. So, I should construct a script, maybe using COPY, but how to write such kind of scripts? some PDF, web references to learn it?
I was thinking to restrict the data to insert (X,Y and species, genus, family) and to have a pre-constructed table in PostGIS with these columns. I suppose it should minimize much more the work and time to insert data and should also make much easier the scripting.
Thanks.
