COPY is a high-speed data loading interface supported by PostgreSQL. Data is passed in without being parsed, and in a single transaction.
An alternative to using raw pg_put_line() commands is to use pg_copy_from(). This is a far simpler interface.

Use of the pg_put_line() causes most large object operations, including pg_lo_read() and pg_lo_tell(), to subsequently fail. You can use pg_copy_from() and pg_copy_to() instead.
connection
PostgreSQL database connection resource. When
connection is not present, the default connection
is used. The default connection is the last connection made by
pg_connect() or pg_pconnect().
dataA line of text to be sent directly to the PostgreSQL backend. A NULL terminator is added automatically.
