I'm pretty sure that most committers would want to apply the
rm_identity part in a separate commit first. Could you make it
two patches, one introducing rm_identity, and another with

const char *
clog_identify(uint8 info)
{
switch (info)
{
)
WITH (
OIDS=FALSE
);
There are redundant call when sorting?

The real scene. Function ST_Distance_Sphere is slow, the query:
