Re: [Swig-user] SWIGing PostgreSQL's SPI interface

[Álvaro H. T. <ah...@8k...>]

     Hi William.

     I'm sorry not to have done that before, but I assumed it was highly 
unlikely that the error reported is indeed a syntax error on 
PostgreSQL's source code, given how audited and CI-tested this code is. 
However, here you can find the file:

https://github.com/postgres/postgres/blob/master/src/include/executor/spi.h#L62

     Thank you,

     Álvaro
