The task - I want to clone a table I created in public schema in another
schema (xxx) of the same database.
The problem - I get an error message when creating the table using the
original SQL script: ERROR: type "geography" does not exist.
I understand from
"http://stackoverflow.com/questions/9067335/how-to-create-table-inside-speci
fic-schema-by-default-in-postgres" that the original script should work if I
set the search path to the destination schema (xxx) prior to execute the
script (set search_path to xxx ;) but the PgAdmin III SQL window does not
seem aware of the geography type.
What I do not understand is that using the GUI (contextual menu. new table .
new column.) within schema xxx, I can create the table as expected, and the
geography type is recognized. Any idea about what is going on when using
the SQL window?
A quick test here showed that in the GUI New Object(table) wizard the
types are schema qualified if needed. For instance I did:
CREATE TYPE public.test_type AS (my_int int);
When I went to another schema and created a table and then a column, the
test_type was shown as public.test_type and I could use it as the column
type. The table was created with no problem. So pgAdmin searches the
schemas for you to retrieve types when you use the creation wizard.
When you are using the SQL window it has no context other then what is
provided by the search_path. If the search_path does not include the
schema that holds the type you want, then you will get an error.
Probably the best way to see this is tail the Postgres log file where
the postgresql.conf file has log_statement = 'mod' or 'all'.
