@osipovartem When I try to create a table that already exists, I get this error:

 > SHOW TABLES;

Error occurred: 010001 (02000): 97918652-5c44-4f0b-99e7-38e83b31ba3b: External error: Table next not found.
 > CREATE TABLE embucket.public.dan (name Varchar);

KEEP IN MIND If you create first time and use SHOW TABLES everything works fine as long as you don't restart the service.

For example, you can do this:

 > CREATE TABLE embucket.public.dandandan (name Varchar);

Error occurred: 010001 (02000): 576f7be9-9fb2-4104-b4c4-ad61a993c6fb: Iceberg error: service error
 > SHOW TABLES;
+--------------------------------------------------------------+
| created_on | name      | kind  | database_name | schema_name |
|------------+-----------+-------+---------------+-------------|
| None       | dandandan | TABLE | embucket      | public      |
+--------------------------------------------------------------+

HOWEVER, probably this is related more to #32 than this bug.

To recreate the table you need to call CREATE OR REPLACE

@osipovartem It's more of a registering it back so that metastore would be able to list it thing. But regardless, I think we can merge this!
