[postgis-users] pgsql2shp - question/problem

[Stephen Woodbridge]

Hi all,

I'm trying to reorder a shape file based on an attribute column using a 
sql query with an order by clause, but the resulting file always seems 
to be ordered by gid. Is pgsql2shp wrapping the sql query and re 
ordering it? Why?

shp2pgsql -s 4283 -d -D -N skip data/topo-2m/localities/aus25lgd_p.shp 
rawdata.aus25lgd_p | psql -U postgres -h localhost -p 5435 mydb

pgsql2shp -u postgres -h localhost -p 5435 -f a.shp mydb "select * from 
rawdata.aus25lgd_p order by population::integer desc"

$ dbfdump a | head
0:0:1:1:locality:GARY JUNCTION:5:0:BI000001:DJ00015139
0:0:2:2:locality:EVERARD JUNCTION:5:0:BI000001:DJ00015140

0:0:10:10:locality:CAPE KEITH:3:0:BJ000004:DJ00015148

This is the order of the original shapefile.

I also tried to use mapserver's sortshp but the POPULATION field is 
character varying(7) so it does not do a numeric sort.

I'll give ogr2ogr a try, but it seems like if I give a sql query to 
pgsql2shp that it should not change it.
