Обсуждение: Error in example

The following documentation comment has been logged on the website:

Description:

Dear, 

In the example of how to use SPI in the following link
https://www.postgresql.org/docs/10/spi-examples.html

The parameters numbers in the follow lines are wrong. 

    / * Convert a text object to a C string * /
    command = text_to_cstring (PG_GETARG_TEXT_PP (1));
    cnt = PG_GETARG_INT32 (2);

They should be as follow:

    / * Convert a text object to a C string * /
    command = text_to_cstring (PG_GETARG_TEXT_PP (0));
    cnt = PG_GETARG_INT32 (1);

Best regards,
Gláucio
