[Pgpool-hackers] Nasty bug with function_call_walker

[Tatsuo Ishii]

Hi,

I have found a nasty bug with
function_call_walker(pool_select_walker.c). In 3.0 or later, it is
possible to find function calls in a raw parse tree using
function_call_walker. It always regarded the first element is the
function name, which is not true if the function has schema
qualification. In this case we should use lsecond() rather than
lfirst() to extract the function name because the first element is the
schema name. Back patched to 3.0-stable as well.
