Re: BUG #2294: SPI_connect() fails in trigger when a Foreignkey constraint exists on same table as trigger.

Tom -

  Indeed, its entirely possible I forgot to reLOAD the library, especially
given that it appears to work for you with this correction.  I'll give it
another go in a clean environment and see how it goes.

Thanks
