Re: psql: add \create_function command

Tom Lane:
Or we could cut out the intermediate variable altogether
by inventing something that works like :'...' but reads
from a file not a variable.  That might be too specialized
though, and I'm not sure about good syntax for it either.
Maybe like
CREATE FUNCTION foo() RETURNS whatever AS :{source_file.txt} LANGUAGE ...;

That would indeed be very useful! I would immediately use this in a lot 
of places.
