Matthew,
Now that you mention it I have run into the same issue myself especially
since county is such a common table name.
Go ahead and enter a ticket to request schema qualifying. It has been
something I've been thinking of doing anyway.
Thanks,
Regina

Regina,
Thank you for looking into this. Before entering a bug I did some other
checks and believe I've found the cause.
The function in question creates a query without schema-qualified table
names.
ERROR: column co.statefp does not exist
LINE 2: ...cefp = p.placefp) LEFT JOIN county co ON ('25' = co.statefp...

PL/pgSQL function geocode(character varying,integer,geometry) line 26 at
RETURN QUERY
I have a county table in another schema (also in the search path). After
renaming that other table it appeared to work. In fact, it returned
locations (not just null) where it errored out before, meaning it isn't just
unlocatable addresses; it is affecting all output. Also, it looks like the
table names in the tiger and tiger_data schemas are not obscure (a good
thing) and therefore may be in use somewhere else in a database (a bad
thing).
Can the extension be updated so the generated scripts and all functions
always use schema-qualified table names? I realize that might be a tall
order, but it seems very easy for table names to collide within the search
path. Should I still enter this as a bug?
Thanks for the excellent work on geocoding (and PostGIS); the address
standardizing, data import, and geocode results are impressive.

Matthew,
Can you ticket this one in our ticket tracker - http://postgis.net/support/
Unfortunately I don't have Idaho data loaded in my instance and can't
trigger the problem with the data I have just by replacing the state.
It does sound like a bug though if other addresses work. I'll try to take a
look at it next week while I'm looking at other tiger issues.
Thanks,
Regina

Subject: [postgis-users] Tiger geocoder - error instead of null when
unlocatable
After following the instructions (several times) and apparently successfully
installing tiger geocoder and the tiger data for Idaho, I keep getting an
error when the geocoder can't find an address.
With a locatable address it works just fine.
SELECT * FROM geocode('3300 state st, boise, id 83703')
When an address is not locatable, I assume it should return null (and move
on to the next in the batch).
Instead, it returns an error:
SELECT * FROM geocode('3300 state st, neverland, id 9876543210')
---------------------------------------
ERROR: column co.statefp does not exist
LINE 2: ...cefp = p.placefp) LEFT JOIN county co ON ('16' = co.statefp...
^
QUERY: SELECT DISTINCT ON
(sub.predirabrv,sub.fename,COALESCE(sub.suftypabrv, sub.pretypabrv)
,sub.sufdirabrv,coalesce(p.name,zip.city,cs.name,co.name),s.stusps,sub.zip)
sub.predirabrv as fedirp, sub.fename, COALESCE(sub.suftypabrv,
sub.pretypabrv) as fetype, sub.sufdirabrv as fedirs,
coalesce(p.name,zip.city,cs.name,co.name)::varchar as place, s.stusps as
state, sub.zip as zip, interpolate_from_address($1, sub.fromhn, .
It doesn't seem to matter which address element causes the problem, the
error is the same and it kills the query. Is there some error handling that
is getting missed? The examples I've seen look like it just returns null.
Thank you for any help.
