If you have to you can use either the lo interface, or you can use
bytea. Large Object (i.e. lo) allows for access much like fopen /
fseek etc in C, but the actual data are not stored in a row with
other data, but alone in the lo space. Bytea is a legit type that you
can have as one of many in a row, but you retrieve the whole thing at
once when you get the row.
Preferred way to store 2GB data is to put it into a file and put the
name of the file into the database.
