[postgis-users] Newbie: search_path variable

[Paragon Corporation]

Mike,
 
Hard to tell what the issue is here.  So here are a couple of comments
reading from your prior posts
 
1) You don't need tiger_data in your search path because all the geocoder
functions just reference the tiger master tables that the tiger_data tables
are children of.
2) The county table not being created issue you were having.  I recall this
happening a while back to somebody because they had a table called county in
their public schema so the create skipped and since their public county
table was structured differently, things would break mysteriously.
 
So verify you don't have any tables in your public schema with same name as
those in tiger schema.
 
3) Your search_path issue.  How exactly did you set your search path?
here are a couple of mistakes we've seen
 
a) Not setting the search path of the database 
Did you use the remarked out line in create_geocoder
 
ALTER DATABASE geocder SET search_path=public, tiger;
 
If you simply use:
SET search_path=public,tiger;
 
That only lasts for the life of the session, but is a good way to verify you
have things at least installed correctly.
 
The other thing to keep in mind is that ALTER DATABASE doesn't take effect
for current session, you need to create a new session to get the new
settings
 
b) explicitly setting the search_path of a user.  PostgreSQL has this neat
(for super experts)/awful (for newbies or forgetfuls) feature that allows
you to set the default search path
for the individual user (at the server level) and even for specific user at
the database level.
 
Youc an do something as crazy as this:
ALTER ROLE postgres IN DATABASE geocoder SET search_path = "$user", public;
 
and if you have such as setting, your ALTER DATABASE .. SET search_path will
be powerless when the postgres user logs in.
 
You can also set search path at the server level for a user
 
Anyway check if yo uhave any of these issues.
 
Hope that helps,
Regina

More on this pprint_addy issue.  The search_path variable appears to not be
set correctly.  I have "$user", public, topology, tiger, tiger_data,
tiger_staging as the search_path value for the geocoder database.



I took the query that makes the tiger.pprint_addy function and altered it so
the pprint_addy function gets made in public.pprint_addy and now pprint_addy
function works correctly.  



Attempts to use the geocode example from here
http://postgis.refractions.net/docs/Geocode.html with Tiger2011 data return
nothing.  No errors.

I discovered another table not made tiger.tract.  Again, no error.  It just
doesn't get made.


I used the included script to load Massachusetts data to use the
documentation examples and am having more issues. 



#1: Select Function pprint_addy example does not work.  Function pprint_addy
is present as pprint_addy(tiger.norm_addy).   I can run SELECT
normalize_address('202 East Fremont Street, Las Vegas, Nevada 89101')) As
pretty_address; and it returns a formatted address.

 SELECT pprint_addy(normalize_address('202 East Fremont Street, Las Vegas,
Nevada 89101')) As pretty_address;
2012-11-09 08:36:50 PST ERROR:  function pprint_addy(norm_addy) does not
exist at character 8
2012-11-09 08:36:50 PST HINT:  No function matches the given name and
argument types. You might need to add explicit type casts.

#2 the geocode example returns nothing.  No error.  Just no results.

SELECT g.rating, ST_X(g.geomout) As lon, ST_Y(g.geomout) As lat, 
    (addy).address As stno, (addy).streetname As street, 
    (addy).streettypeabbrev As styp, (addy).location As city,
(addy).stateabbrev As st,(addy).zip 
    FROM geocode('75 State Street, Boston MA 02109') As g; 


The search_path for the database geocoder is set to include tiger,
tiger_data, public, topology.  Do I need to add those names to the
search_path variable value for database postgres?

Subject: Newbie: census_loader.sql Issue


 This is an update on my issues loading Tiger2011 data to postGIS using
Debian's Wheezy, Postgresql 9.1.  After starting over from the beginning,
I'm down to one error loading data using the included loader scripts as-is.
Table tiger.bg <http://tiger.bg/>  doesn't get made on my system with no
clue that bg didn't get made unless I check my log file.



psql -d geocoder  -f
/home/postgis/postgis/postgis-2.1.0SVN/extras/tiger_geocoder/tiger_2011/cens
us_loader.sql                    setsearchpathforinstall
------------------------------------------
 tiger has been made primary for install
(1 row)

CREATE FUNCTION
psql:/home/postgis/postgis/postgis-2.1.0SVN/extras/tiger_geocoder/tiger_2011
/census_loader.sql:108: NOTICE:  function
loader_generate_census(text[],text) does not exist, skipping
DROP FUNCTION
CREATE FUNCTION
DELETE 3
INSERT 0 1
INSERT 0 1
INSERT 0 1


There's no bg table made.  If I change the stanza from CREATE TABLE bg to
CREATE TABLE tiger.bg, there's still nothing made and no error in postgresql
logs!  If I take the bg table query out and put it in an editor without the
RETURN stanza, the table is made.


Here's the error from the logs using CREATE TABLE bg
