Assuming you know the schema name, you could always check the catalog table, something like
select count(*) from pg_tables where schemaname= 'foo' and tablename='bar'
If it returns, then you know a table by the name foo.bar exists. if not you can create it.

first time the application will run. I want to create the table then and
populate. But not the next time.
Should I just let Java throw and exception and catch it ? Write a function
for this would be optimal, although I have no idea what the correct syntax
is.

I have this, but it just keeps complaining about the IF
IF NOT EXISTS (SELECT table_name FROM information_schema.tables where
table_name = 'post_codes')
THEN
CREATE TABLE post_codes
Probably better to do:
DROP TABLE IF EXISTS post_codes;
CREATE TABLE post_codes(...);
