hello
I have 4 results from QUERYS in my CentOs 7 + PostgreSQL 13.4 on
x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat
4.8.5-44), 64-bit
I connect as USER postgres
QUERY 1:
SELECT PostGIS_Version();
=> 3.1 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
QUERY 2:
SELECT PostGIS_Full_Version();
=> POSTGIS="3.1.4 ded6c34" [EXTENSION] PGSQL="130"
GEOS="3.9.1-CAPI-1.14.2" SFCGAL="1.3.1" PROJ="7.2.1" GDAL="GDAL 3.3.1,
released 2021/06/28" LIBXML="2.9.1" LIBJSON="0.11" TOPOLOGY RASTER
QUERY 3:
SELECT num, street, city, state, zip FROM parse_address('1 Devonshire
Place PH301, Boston, MA 02109');
[num] => 1
[street] => Devonshire Place PH301
[city] => Boston
[state] => MA
[zip] => 02109
now my problem in QUERY 4:
a// I open http://postgis.net/
b// I copy exactly "the command test" from home page:
QUERY = SELECT superhero.name FROM city, superhero WHERE
ST_Contains(city.geom, superhero.geom) AND city.name = 'Gotham';
c// I run QUERY in my server
d// result is:
----------------------------------------------------------------------------------------------------------------------
[pg_last_error()] => ERROR: relation "city" does not exist
LINE 1: SELECT superhero.name FROM city, superhero WHERE ST_Contains...
----------------------------------------------------------------------------------------------------------------------
why this error?
how I can fix?
my target is OTHERS users (not postgres) can use POSTGS
then how can user1, user2, user33 use POSTGIS without connect to DB postgres ??
or... to use POSTGIS is mandatory users connect to postgres DB ?
many thanks

Initially, PostgreSQL databases are empty and contain no data (except metadata).
There is certainly no table like "city" or "superhero".
Before you can query these tables, you have to create them and fill them with data.
If you follow a tutorial, that tutorial should tell you how to get these data and
how to load them into your database.
Yours,
