Обсуждение: inserting multiple rows

Does PostgreSQL not support

insert into mytable (row1, row2) values ('a', '1'), ('b', '2'), ('c',
'3'), ('d', '4')

?  If not, does anyone know why not?

According to the 7.4.3 documentation it's not possible
to insert more than one row with INSERT. See
http://www.postgresql.org/docs/current/interactive/sql-insert.html

I think this is not a PGSQL issue, since SQL standard defines
INSERT command to insert one row at a time.

There are alternatives to insert multiple rows using a SELECT or a COPY.

No, but the COPY command can do something like this.

COPY INTO mytable FROM stdout;
a b c d
1 2 3 4



Take a look at http://www.postgresql.org/docs/7.4/static/sql-copy.html
