RE: : Execute a string of command in sql'script

	Could you execute aa system command (perhaps in a c function using
system) to pass this command to psql. (maybe write it to a file first then
redirect stdin, or perhaps pipe an echo command if using shell to exec
psql.) (ok so theres got to be a better way, but it might work :) )
