I'm trying to query the_geom value for all spatial tables in our DB.

For one, I know I can get the tables in question with:

select * from geometry_columns where f_table_name like 'ParcelPoints%';

But is it possible to get all the geometry values from all tables at once?

Ultimately, I'd like to perform something like the following where '...public."ParcelPoints_01001"...' is the result of all geometry values of all tables:

select the_geom from public."ParcelPoints_01001" WHERE ST_DWithin(the_geom, ST_MakePoint(-86.852470,32.628280)::geography, 1000) limit 3000;

You need to explicitly refer to all tables with geometric field types, for example: select public.tbl1.geom as geom1, public.tbl2.geom as geom2, public.tbl3.geom as geom3 from public.tbl1, public.tbl2, public.tbl3 WHERE ST_DWithin(public.tbl1.geom, ST_MakePoint(-86.852470,32.628280)::geography, 1000) or ST_DWithin(public.tbl2.geom, ST_MakePoint(-86.852470,32.628280)::geography, 1000) or ST_DWithin(public.tbl3.geom, ST_MakePoint(-86.852470,32.628280)::geography, 1000) limit 3000;

To view all your tables in the public schema, run the script:

SELECT n.nspname AS "Schema", c.relname AS "Name", CASE c.relkind WHEN'r'THEN'table' WHEN'v'THEN'view' WHEN'i'THEN'index' WHEN'S'THEN'sequence' WHEN's'THEN'special' END AS"Type", r.rolname AS "Owner", pg_catalog.obj_description(c.oid,'pg_class')AS "Description" FROM pg_catalog.pg_class c JOIN pg_catalog.pg_roles r ON r.oid = c.relowner LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace WHERE c.relkind IN('r') AND n.nspname <>'pg_catalog' AND n.nspname !~ '^pg_toast' AND pg_catalog.pg_table_is_visible(c.oid);

In order to get all the geometric tables, run the script:

SELECT * from information_schema.columns WHERE column_name = 'geom'
