It's dead code because it's not called from anywhere.
Once upon a time it was intended to be called by dynamically-loaded
C functions, but the SPI interface superseded it a long time ago.
The only reason for not ripping it out is the faint possibility that
somewhere out there is someone with hoary old C-function code that
still does queries via the backend-PQexec interface instead of SPI.
But considering that backend-PQexec has been undocumented at least
since Berkeley days, I rather doubt it.
