SPI_connect, SPI_connect_ext - connect a C function to the SPI manager

SPI_connect opens a connection from a C function invocation to the SPI manager. You must call this function if you want to execute commands through SPI. Some utility SPI functions can be called from unconnected C functions. SPI_connect_ext does the same but has an argument that allows passing option flags. Currently, the following option values are available: SPI_OPT_NONATOMIC Sets the SPI connection to be nonatomic, which means that transaction control calls (SPI_commit, SPI_rollback) are allowed. Otherwise, calling those functions will result in an immediate error. SPI_connect() is equivalent to SPI_connect_ext(0).
