Dear all,
I am looking for a mechanism to load a specific file into an existing
database. The file is a CTM (Compact Topic Maps Syntax ) file and I
have written a CTM parser in plpgsql which works fine. The main
problem is, that I have to load the file into memory and sent a query
to database which causes an memory error because of a hugh file size.
Is it possible to copy data from a file into database by using own
functions?
you could use the Large Object API to stream the data into postgres.
but that just stores it as a large blob of data. if you need more
structured storage, I don't know what to suggest, except maybe parsing
your CTM in your application and sending the data to postgres a row at a
time.
