Yeah, I'm with you and Pavel. Here's my quick perl one-liner to produce
a set of SPI_* constants for pl/perl. I'm looking at the best way to
include this in the bootstrap code.

perl -ne 'BEGIN { print "use constant\n{\n"; } END { print "};\n"; }
print "\t$1 => $2,\n" if /#define (SPI_\S+)\s+\(?(-?\d+)\)?/;'
src/include/executor/spi.h
