pg_put_line() sends a NULL-terminated string
to the PostgreSQL backend server. This is needed in conjunction
COPY FROM command.
COPY is a high-speed data loading interface
supported by PostgreSQL. Data is passed in without being parsed,
and in a single transaction.
The application must explicitly send the two characters "\." on the last line to indicate to the backend that it has finished sending its data, before issuing pg_end_copy().
A line of text to be sent directly to the PostgreSQL backend. A
terminator is added automatically.
$conn = pg_pconnect("dbname=foo");
pg_query($conn, "create table bar (a int4, b char(16), d float8)");
pg_query($conn, "copy bar from stdin");
pg_put_line($conn, "3\thello world\t4.5\n");
pg_put_line($conn, "4\tgoodbye world\t7.11\n");
