Y'know, I tried that. I got a cryptic error at
points <- pg.spi.exec(sprintf("select x(%2$s) as x, y(%2$s) as y from
%1$s;"
The error was
ERROR: R interpreter expression evaluation error
DETAIL: Error in pg.spi.exec(sprintf("select x(%2$s) as x, y(%2$s) as y from
%1$s;", :
error in SQL statement : syntax error at or near ";"
CONTEXT: In R support function pg.spi.exec
